Pin Functions

PIN I/O DESCRIPTION
NAME NO.
CP1, CP2 3, 4 Connect to flying capacitor for internal charge pump.
EN 5 I Enable pin (HIGH = enable). When the pin is pulled low for 1 ms, the IC turns off and consumes less than 1-μA current.
FB 7 I Voltage feedback pin for output regulation, 0.5-V regulated voltage. An external resistor divider connected to this pin programs the regulated output voltage.
GND 1 – Ground of the IC.
OUT 8 O Isolation switch is between this pin and VO pin. Connect load to this pin for input/output isolation during IC shutdown. See Without Isolation FET for the tradeoff between isolation and efficiency.
SS 6 I Soft start pin. A RC network connecting to the SS pin programs soft start timing. See Start-Up.
SW 9 I Switching node of the IC where the internal PWM switch operates.
Thermal Pad – – It should be soldered to the ground plane. If possible, use thermal via to connect to ground plane for ideal power dissipation.
VIN 2 I IC Supply voltage input.
VO 10 O Output of the boost converter. When the output voltage exceeds the overvoltage protection (OVP) threshold, the power switch turns off until VO drops below the overvoltage protection hysteresis.
