MAX774 Datasheet -5v/-12v/-15v Or Adjustable / High-efficiency / Low Iq Inverting DC-dc Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX774/MAX775/MAX776 19-0191; Rev 2; 12/02 EVAALVUAAILTAIOBNLEKIT -5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ Inverting DC-to-DC Controllers.

General Description

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

A unique current-limited, pulsefrequency 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).
