1.5MHz Dual Step-Down DC-DC Converters

with Dual LDOs and Individual Enables

General Description

The MAX8667/MAX8668 dual step-down converters

with dual low-dropout (LDO) linear regulators are

intended to power low-voltage microprocessors or

DSPs in portable devices. They feature high efficiency

with small external component size. The step-down

converters are adjustable from 0.6V to 3.3V (MAX8668)

or factory preset (MAX8667) with guaranteed output

current of 600mA for OUT1 and 1200mA for OUT2. The

1.5MHz hysteretic-PWM control scheme allows for tiny

external components and reduces no-load operating

current to 100µA with all outputs enabled. Dual low-qui-

escent-current, low-noise LDOs operate down to 1.7V

supply voltage. The MAX8667/MAX8668 have individ-

ual enables for each output, maximizing flexibility.

The MAX8667/MAX8668 are available in the space-

saving, 3mm x 3mm, 16-pin thin QFN package.
