Top View of LM46000EVM 3 Input/Output (I/O) Connector Description VIN - Terminal on J2-- is the power input terminal for the converter. The terminal edge connector also provides a power (VIN) and ground (GND) connection to allow the user to attach the EVM to a cable harness. VOUT - Terminal on J3-- is the regulated output voltage for the converter. The terminal edge connector also provides a power (VOUT) and ground (GND) connection to allow the user to attach the EVM to a cable harness. GND - Terminal on J2 and J3-- are the ground reference for the converter. The terminal edge connector also provides a GND connection for attaching the EVM to a cable harness. EN - Testpoint-- is used to enable the converter by supplying a voltage greater than 2.2 V (typ) or just to monitor the voltage on this terminal whenever a resistor divider is in place (for precision enable applications). The LM46000EVM is built for a precision enable application with resistors RENT and RENB pre-assembled. The regulator will be enabled when VIN > 3.5 V. This threshold can be calculated by: 2 LM46000EVM User Guide SNVU423 - June 2014 Submit Documentation Feedback Copyright (c) 2014, Texas Instruments Incorporated Preview Setup www.ti.com Enable _ Voltage RENT * VIH _ EN 1 (c) RENB where * VIH_EN is 2.2 V (typ) (1) PG - Testpoint-- is used to monitor the power good flag. This flag indicates whether the output voltage has reached its regulation point. This terminal is an open-drain output that requires a pullup resistor to the appropriate logic voltage (any voltage less than 14 V). A pre-installed resistor RPG1 of 100 k is tied to the PG terminal and brought out to the PG_PULL UP test point. PG_PULL UP - Testpoint-- is the top connection of the pre-assembled 100-k RPG1 pullup resistor that ties directly to the open-drain PG terminal. Supply an appropriate voltage to this test point, or tie it directly to the VOUT test point to observe the PG flag operation. BIAS - Testpoint-- is used to monitor the BIAS voltage. A pre-installed capacitor of 4.7 F is connected from the BIAS terminal to ground (GND). This node is connected to VOUT through a zero Ohm resistor pre-installed on the bottom layer, labeled (RBIAS). SYNC - Testpoint -- is the input terminal for an optional external input clock to the converter. The external clock frequency must be between 200 kHz and 2.2 MHz, if used. A pulldown resistor of 100 k (RSYNC) is installed on the EVM. SW - Testpoint-- is used to monitor the voltage on the switch terminal and the switching frequency of the voltage regulator. Remove this test point before making any electromagnetic interference (EMI) measurements. VSUPPLY - Edge Connector terminal #9-- is used to supply the input voltage through an on board LC filter (if one is needed for conducted EMI/EMC measurements). The Lin and Cd component pads are located on the bottom side of the EVM. Please refer to the EVM schematic for initial suggestion of component values. 4 Setup Set the input voltage (VIN) range for the converter between the operating voltage range of 3.5 V to 60 V. If a load is driven, it should be applied to the VOUT terminal and should not exceed the maximum load current of 0.5 A. 5 Operation For proper operation of the LM46000, VIN, GND, and VOUT should be properly configured as stated above. In this configuration, the device will start up when power is applied and the output voltage of the regulator (VOUT) will come up to the proper value. The default setting for output voltage of the LM46000EVM is 3.3 V. Other output voltages can be set by replacing the feedback terminal resistor dividers RFBT and RFBB; please consult the datasheet for proper selection of these resistor values. The default frequency for the LM46000EVM is 500 kHz. If other frequencies are desired, within the frequency range of 200 kHz and 2.2 MHz, the RT resistor value can be changed. Please consult the datasheet for proper selection of the RT resistor. You must change inductor (L_60V_LC) and total output capacitance for proper control loop operation.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
