Pin Descriptions

PIN TYPE DESCRIPTION
NUMBER NAME
1 C1+ O Flying capacitor connection
2 VIN I Input voltage connection. Input voltage range: 3 V to 5.5 V
3 C1– O Flying capacitor connection
4 FLASH I Flash logic input pin. Logic HIGH = flash output on, logic low = flash output off. there is an internal pulldown of 300 kΩ between FLASH and GND.
5 GND — Connect to ground
6 EN I Enable pin. Logic HIGH = enable, Logic LOW = shutdown. There is an internal pulldown of 300 kΩ between EN and GND
7 GND — Connect to ground
8 IOUT O Flash output. ON/OFF control via FLASH pin
9 VOUT O 5-V regulated output
10 GND — Connect to ground
