VIN: Input voltage to the TPS2420. The recommended operating voltage range is 3 V to 18 V. All VIN pins

should be connected together and to the power source.

VOUT: Output connection for the TPS2420. When switched on the output voltage will be approximately:

(5)

LTCH: When pulled low the 2420 will attempt to restart after a fault. If left floating or pulled high the TPS2420 will

latch off after a fault. This pin is internally clamped at 3 V and is pulled to the internal 3-V supply by diode in

series with a 100-k

Ω resistor.

PG: Active low, Open Drain output, Power Good indicates that there is no fault condition and the output voltage
