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-quiescent-current, low-noise LDOs operate down to 1.7V
supply voltage. The MAX8667/MAX8668 have individual
enables for each output, maximizing flexibility.
The MAX8667/MAX8668 are available in the space-saving,
3mm x 3mm, 16-pin thin QFN package.
