DEMO MANUAL DC2666A-A/DC2666A-B LTC7132 Dual Phase Monolithic Step-Down Supply with PSM DESCRIPTION Demonstration circuit 2666A-A/2666A-B features the LTC(R)7132, a wide input and output voltage range, high efficiency dual output polyphase DC/DC step-down regulator with sub-milliohm DCR sensing and digital power system management. This demo board is available in two versions: DC2666A-A is configured as 2-phase dual output, DC2666A-B is configured as 2-phase single output. Both versions operate over an input voltage range of 6V to 20V. The DC2666A-A factory default output voltage for both outputs are VOUT0 = 1V, VOUT1 = 1V with a 20A load current rating per channel. The DC2666A-B factory default output voltage is VOUT = 1V with a 40A load current rating. Both channels can deliver up to 25A maximum load current for each version. The output voltages can be programmed from 0.6V up to 1.8V. Programming the output voltages to any value that is greater than 1.8V will require changes to the inductors, external DCR network component and may require the maximum output current to be derated based on thermal derating curves provided in the data sheet of LTC7132. The factory default switching frequency is preset at 425kHz typical. The DC2666A-A/DC2666A-B uses external inductors with extremely low DCR to demonstrate the part's capability of provide excellent performance for submilliohm DCR current sense applications. Both versions of DC2666A comes with PMBus interface and digital power system management functions. An onboard 12-pin connector is available for users to connect the DC1613A dongle to the demo board, which provides an easy way to communicate and program the part using LTpowerPlay(R) software development tool. LTpowerPlay software and I2C/PMBus/SMBus Dongle DC1613A allows users to monitor real time telemetry of input and output voltages, input and output current, switching frequency, internal IC die temperatures, external power component temperatures and fault logs. Programmable parameters include device address, output voltages, control loop compensation, switching frequency, phase interleaving, DCM or CCM Mode of operation, digital soft-start, sequencing and time based shut down, fault responses to input and output overvoltage, output overcurrent, IC die and power component overtemperatures. The LTC7132 is available in a thermally enhanced, low profile 140-lead 9mm x 11.25mm x 2.22mm BGA package. It is recommended to read the data sheet and demo manual of LTC7132 prior to use or making any changes to DC2666A-A/DC2666A-B.

Please refer to Figure 4a (DC2666A-A) and Figure 4b (DC2666A-B) for proper measurement equipment setup and follow the test procedures below: 1. With power off, connect the input power supply between VIN (J1) and GND (J2). 2. Connect the first load between VOUT0 (J3) and GND (J4) for channel 0, connect the second load between VOUT1 (J5) and GND (J6) for channel 1. Preset all the loads to 0A. 3. Connect the DMM between the input test points: VIN+ (E1) and VIN- (E2) to monitor the input voltage. Connect DMMs between VOUT0+ (E3) and VOUT0- (E4), VOUT1+ (E5) and VOUT1- (E6) to monitor corresponding DC output voltages of channel 0 and channel 1. 2 4. Prior power up the DC2666A-A/DC2666A-B, check the default position of the jumpers and switches (Refer to Table1): Table1. Demo Board Default Jumpers and Switches Position JUMPER/ SWITCH NAME SW0, SW1 JP1 JP2 JP3 DESCRIPTION RUN0, RUN1 WP BIAS PULSE OFF OFF OFF EXT POSITION 5. Turn on the power supply at the input, measure and make sure the input supply voltage is 12V. Flip SW0 (RUN0) and SW1 (RUN1) to the ON position. The output voltages should be 1.0V 0.5% for VOUT0 and VOUT1. 6. Once the input and output voltages are properly established, adjusting the input voltage between 6V to 20V max and the load current within the operating range Rev. 0 DEMO MANUAL DC2666A-A/DC2666A-B QUICK START PROCEDURE of 0A to 20A max per channel. Observe the output voltage regulation, output ripple voltage, switching node waveforms, load transient response and other parameters. tweak the potentiometer R71 to adjust the amplitude of the pulse load current. Connect a short BNC cable from IOUT STEP (J9) to the input channel of an oscilloscope to monitor the output load current step. The equivalent conversion ratio of voltage to current of IOUT STEP is 10mV/1A. The load step response of VOUT0 is observed by connecting a short BNC cable from VOUT0 (J7) to the input of an oscilloscope channel. Similarly, the load step response of VOUT1 is observed by remove R56 and use this zero-ohm jumper to stuff R58 and connect a short BNC cable from VOUT1 (J8) to the input of an oscilloscope channel. When operating the part as dual phase dual output, R56 and R58 cannot be stuffed at the same time to avoid shorting two outputs together. The onboard load step circuit is disabled by set JP2 (BIAS) to the OFF position. If the fine adjustment of the output load step current rise time and fall time di/dt is required, disable the onboard load step circuit by set JP2 (BIAS) to the OFF position, set JP3 (PULSE) to the EXT position and use an external pulse generator with adjustable dV/dt to apply the pulse voltage at E17 (EXT PULSE) and connect a short BNC cable from IOUT STEP (J9) to the input of an oscilloscope channel to monitor the corresponding load step current. The output current step slew rate and its magnitude is varied by adjusting the rise time, fall time and amplitude of the applied voltage pulse at the gate of the MOSFETs (Q3, Q4). Keep the voltage pulse at the frequency less than 10Hz and maximum duty cycle less than 5% to avoid excessive thermal stress on the MOSFETs. NOTE: To measure the input/output voltage ripples properly, do not use the long ground lead on the oscilloscope probe. See Figure3 for the proper probing technique of input/output voltage ripples. Short, stiff leads need to be soldered to the (+) and (-) terminals of an input or output capacitor. The probe's ground ring needs to touch the (-) lead and the probe tip needs to touch the (+) lead. 7. DC2666A-A/DC2666A-B provides convenient onboard BNC terminals to accurately measure the output ripple voltage of channel 0 and channel 1. Connect short BNC cables from VOUT0 (J7) and VOUT1 (J8) to the input channels of an oscilloscope. (Scope probe ratio 1:1, AC-coupling) to observe the output ripple voltage. 8. (Optional) Operation with EXTVCC The LTC7132 EXTVCC pin is available for optional use of an external 5.5V bias supply voltage to power the EXTVCC pin, bypassing the internal 5.5V regulator when EXTVCC is higher than 4.7V and VIN is higher than 7V. An onboard LDO (U2) output can be used to supply 5.5V bias voltage for EXTVCC pin. The onboard 5.5V LDO output is enabled by insert R50 with zero ohm and place JP2 (BIAS) to the ON position. Place JP2 (BIAS) to the OFF position to disable the output of this LDO. EXTVCC pin requires a minimum of 4.7F decoupling ceramic capacitor between this pin and PGND. Do not exceed the maximum rated voltage of EXTVCC pin and make sure VIN is powered up before applying EXTVCC. 10.Connecting a PC to DC2666A-A/DC2666A-B Refer to Figure 1a (DC2666A-A) and Figure 1b (DC2666A-B) for proper demo board set up with PC. Users can use a PC to reconfigure the power management features of the LTC7132 such as: nominal VOUT, margin set points, OV/UV limits, temperature fault limits, sequencing parameters, the fault logs, fault responses, GPIOs and other functionality. The DC1613A dongle can be hot plugged when VIN is present. 9. (Optional) Onboard Load Step Circuit DC2666A-A/DC2666A-B provides an option onboard load transient circuit to quickly check VOUT peak to peak deviation during rising or falling dynamic load transient. The load step circuit is enabled by place JP2 (BIAS) to the ON position, JP3 (PULSE) to the INT position and Rev. 0 3 DEMO MANUAL DC2666A-A/DC2666A-B QUICK START PROCEDURE (1a) Demo Setup with PC for DC2666A-A (1b) Demo Setup with PC for DC2666A-B Figure1. 4 Rev. 0 DEMO MANUAL DC2666A-A/DC2666A-B QUICK START PROCEDURE LTpowerPlay Quick Start Guide LTpowerPlay is a powerful Windows-based development environment that supports ADI power system management ICs.
