NAMENO.DESCRIPTION
BOOT1A 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.
EN3Enable pin. Pull below 1.25V to disable. Float to enable. Programming the input undervoltage lockout with two resistors is recommended.
SS4Slow start pin. An external capacitor connected to this pin sets the output rise time
VSENSE5Inverting node of the gm error amplifier
COMP6Error amplifier output, and input to the PWM comparator. Connect frequency compensation components to this pin
GND7Ground.
PH8The source of the internal high-side power MOSFET.
