The IR3899A is a synchronous buck converter, providing a compact, high-performance
and flexible solution in a small 4 mm x 5 mm power QFN package.

Key features offered by the IR3899A include internal digital soft-start, precision 0.6 V
reference voltage, power good, thermal protection, programmable switching frequency,
enable input, input undervoltage lockout for proper start-up, latched off or unlatched
overvoltage protection, and pre-bias start-up.

The output overcurrent protection (OCP) function is implemented by sensing the voltage
developed across the on-resistance of the synchronous MOSFET for optimum cost and
performance, and the current limit is thermally compensated.
