General Description

Features

85% Efficiency for 5mA to 1A Load Currents

Up to 5W Output Power

100µA (max) Supply Current

5µA (max) Shutdown Current

3V to 16.5V Input Range

or Adjustable Output Voltage

Current-Limited PFM Control Scheme

300kHz Switching Frequency

MAX774/MAX775/MAX776

The MAX774/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.

These ICs also use tiny external components; their high

switching frequency (up to 300kHz) allows for less than

5mm diameter surface-mount magnetics.

The MAX774/MAX775/MAX776 accept input voltages from

3V to 16.5V, and have preset output voltages of

-5V, -12V, and -15V, respectively. Or, the output voltage

can be user-adjusted with two resistors. Maximum

- V

OUT

differential voltage is limited only by the break-

down voltage of the chosen external switch transistor.

These inverters use external P-channel MOSFET switches,

allowing them to power loads up to 5W. If less power is

required, use the MAX764/MAX765/MAX766 inverting

switching regulators with on-board MOSFETs.
