MAX8734 Datasheet PDF - Maxim Integrated

General Description

●The MAX8732/MAX8733/MAX8734 dual step-down, switch-mode power-supply (SMPS) controllers generate

●logic-supply voltages in battery-powered systems. The MAX8732/MAX8733/MAX8734 include two pulse-width

●modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5V and 3.3V. These devices feature two linear regulators providing 5V and 3.3V always-on outputs.
