Description

The MAX774, MAX774CPA, MAX775, MAX776 inverting switching regulators deliver high efficiency over three decades of load current.

A unique current-limited, pulse frequency modulated (PFM) control scheme provides the benefits of pulse-width modulation (high efficiency with heavy loads), while using less than 100µA of supply current (vs. 2mA to 10mA for PWM converters).

The result is high efficiency over a wide range of loads.
