NAME NO. DESCRIPTION
BOOT 1 A 0.1 µF bootstrap capacitor is required between BOOT and PH. If the voltage on this capacitor falls below the minimum requirement, the high-side MOSFET is forced to switch off until the capacitor is refreshed.
VIN

2

Input supply voltage, 3.5 V to 28 V.
EN 3 Enable pin. Pull below 1.25V to disable. Float to enable. Programming the input undervoltage lockout with two resistors is recommended.
SS 4 Slow start pin. An external capacitor connected to this pin sets the output rise time
VSENSE 5 Inverting node of the gm error amplifier
COMP 6 Error amplifier output, and input to the PWM comparator. Connect frequency compensation components to this pin
GND 7 Ground.
PH 8 The source of the internal high-side power MOSFET.
