Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 CTRL I Control pin of the boost converter. It is a multi-functional pin which can be used for enable control, PWM and digital dimming.
2 VIN I The input supply pin for the device. Connect VIN to a supply voltage between 2.7 V and 5.5 V.
3 VOUT O Output of the boost converter.
4 FB I Feedback pin for current. Connect the sense resistor from FB to GND.
5 GND O Ground
6 LX I This is the switching node of the device. Connect the inductor between the VIN and LX pin.
7 Thermal Pad The thermal pad should be soldered to the analog ground plane. If possible, use thermal via to connect to ground plane for ideal power dissipation.
