MAL219699001E3
ENYCAPTM
Capacitance Range: 1 F to 100 F
Voltage Range: 2.3 V to 3.2 V
4 W Backup Power When Input Fails
DESCRIPTION
The MAL219699001E3 demonstration circuit is a fully transparent power management solution with a regulated 2 W output and
integrated power backup. It provides a DC/DC regulator with a wide power input range from 4.0 V to 20 V and adjustable
regulated output between 3.3 V and 5.0 V.
The integrated supercapacitor charger and backup boost regulator is optimized for use with ENYCAPTM supercapacitors as a
backup energy storage device. The LTC3355 provides the supercapacitor with a programmable constant charging current from
35 mA to 600 mA and regulated cut-off voltage of 1.8 V to 3.2 V.
When the power input fails, the backup boost regulator supplies regulated output voltage until the charged energy of the
supercapacitor is depleted. Power good and related control signals are available.

QUICK START PROCEDURE
Choose Output Voltage
Setup Boost Peak Current
Select Supercapacitor Charge Current
Select Switching Modes
Enable / Disable SCAP Charger
Power Connections
1. Connect supercapacitor via connector ST1 or turrets E5 and E6 to the board.
2. Connect load via turrets E2-1 (V_OUT_P) or E2 (V_OUT) and E3 (GND) to the board. V_OUT_P is the protected output of
V_OUT; it switches off when voltage VCAP (supercapacitor) depletes below 1.2 V.
3. Connect supply via turrets E1 (V_IN) and E4 to the board.
Set Up Power Supply Backup Demonstration Mode
On board is a timer to periodically simulate the effect of a supply fail, causing an automatic switch into backup mode to
seamlessly provide power to the external load.
By means of JP13, the user can select the supply mode:
