VISHAY BCCOMPONENTS www.vishay.com Aluminum Capacitors Technical Note Power Management Solution Integrated Supercapacitor Charger By Gerald Tatschl 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.

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. TECHNICAL NOTE 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.
