TPS54331DR 3A, 28V INPUT, STEP DOWN SWIFTM DC/DC CONVERTER circuit board ic

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.
