PW4203 2A , 4.5V -22V Input , Multi-Cell Switching Charger

GENERAL DESCRIPTION

PW4203 is a 4.5-22V input, 2A multi-cell synchronous Buck Li-Ion battery charger, suitable for

portable application. Select pin is convenient for multi-cell charging. 800 kHz synchronous buck

regulator integrates of 22V rating FETs with ultra low on- resistance to achieve high efficiency and

simple circuit design.

The PW4203 is available in an 8-pin SOP package, provides a very compact system solution and

good thermal conductance.
