_______________General Description

The MAX764/MAX765/MAX766 inverting switching regu-

lators are highly efficient over a wide range of load cur-

rents, delivering up to 1.5W. A unique, current-limited,

pulse-frequency-modulated (PFM) control scheme com-

bines the benefits of traditional PFM converters with the

benefits of pulse-width-modulated (PWM) converters.

Like PWM converters, the MAX764/MAX765/MAX766 are

highly efficient at heavy loads. Yet because they are PFM

devices, they use less than 120µA of supply current (vs.

2mA to 10mA for a PWM device).

The input voltage range is 3V to 16V. The output volt-

age is preset at -5V (MAX764), -12V (MAX765), or -15V

(MAX766); it can also be adjusted from -1V to -16V

using two external resistors (Dual Mode

). The maxi-

mum operating V

- V

OUT

differential is 20V.

These devices use miniature external components; their

high switching frequencies (up to 300kHz) allow for less

than 5mm diameter surface-mount magnetics. A stan-

dard 47µH inductor is ideal for most applications, so no

magnetics design is necessary.

An internal power MOSFET makes the MAX764/MAX765/

MAX766 ideal for minimum component count, low- and

medium-power applications. For increased output drive

capability or higher output voltages, use the

MAX774/MAX775/MAX776 or MAX1774, which drive an

external power P-channel MOSFET for loads up to 5W.
