MAX8668 - First Dual Step-Down DC-DC Converters

Download the MAX8668 datasheet PDF. This datasheet also covers the MAX8667 variant, as both devices belong to the same first dual step-down dc-dc converters family and are provided as variant models within a single manufacturer datasheet.

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.

MAX8667/MAX8668 19-0784; Rev 1; 7/07 EVAALVUAAILTAIOBNLEKIT 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-quiescent-current, low-noise LDOs operate down to 1.7V supply voltage.
