PIN FUNCTIONS
TSOT23
Pin #
Name Description
1 PG
Power-Good Indicator. The pin output is an open drain that connects to VIN by an internal
pull-up resistor. PG is pulled up to VIN when the FB voltage is within ±10% of the
regulation level. If FB voltage is out of that regulation range, it is LOW.
2 VIN
Supply Voltage. The MP2143 operates from a 2.5V-to-5.5V unregulated input. C1
prevents large voltage spikes from appearing at the input.
3 SW Switch Output
4 PGND Power Ground
5 OUT Input Sense. For output voltage feedback
6 AGND Analog ground. Reference for the internal control circuit.
7 FB
Feedback pin. Connect an external resistor divider from the output to AGND to set the
output voltage.
8 EN On/Off Control
