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 output...
