General Description

MB39C502 is a single output step down DC/DC controller using external FETs.

It achieves the high efficiency with “Enhanced Low Power Mode (LPM) Operation” in light load.

In Enhanced LPM, this controller operates that the quiescent current is reduced only 30μA and the switching frequency is fallen by extending on time.
