Overview
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.
The MAX8667/MAX8668 have individual enables for each output, maximizing flexibility.
The MAX8667/MAX8668 are available in the spacesaving, 3mm x 3mm, 16-pin thin QFN package.
Applications Cell Phones/Smartphon...
