General Description

The AP5100 is a current mode step-down converter with a built-in power MOSFET to enable smallest solution size power conversion.

With the low series resistance power switch it enables a constant output current of up to 1.2A over a wide input supply range. The load and line regulation has excellent response time over the operating input voltage and temperature range.

The AP5100 is self protected, through a cycle-by-cycle current limiting algorithm and an on chip thermal protection.
