1. Description
MB39C504 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 50μA and the switching frequency is fallen by extending
on time. These operations enable to improve the efficiency in light load. Internal compensation circuit with
current mode architecture and internal boost switch allow reducing the BOM parts and the component area.
