MAX8620YETD+T 产品详情

The MAX8620YETD micro-power-management integrated circuit (μPMIC) powers low-voltage microprocessors or DSPs in portable devices. The μPMIC includes a high efficiency step-down DC-DC converter, two lowdropout linear regulators (LDOs), a microprocessor reset output, and power-on/off control logic. This device maintains high efficiency at light loads with a low 115μA supply current, and its miniature TDFN package makes it ideal for portable devices. The MAX8620Y's step-down DC-DC converter utilizes a proprietary 4MHz hysteretic-PWM control scheme that allows for ultra-small external components. Internal synchronous rectification improves efficiency and eliminates the external Schottky diode that is required in conventional step-down converters. The output voltage is adjustable from 0.6V to 3.3V, with guaranteed output current up to 500mA. The MAX8620Y's two LDOs offer low 45μVRMS output noise and a low dropout of only 200mV at 200mA. Each LDO delivers at least 300mA of continuous output current. The output voltages are pin selectable from 1.8V to 3.3V for flexibility. A microprocessor reset output (active-low RESET) monitors OUT1 and warns the system of impending power loss allowing safe shutdown. Active-low RESET asserts during power-up, power-down, shutdown, and fault conditions where VOUT1 is below its regulation voltage.
