MAXIM INTEGRATED / ANALOG DEVICES MAX1821EUB 600mA Buck Regulator

The MAX1821EUB+ is a high-efficiency, 600mA buck regulator in a 10-pin µMAX package, designed primarily for WCDMA cellular phones to power the power amplifier (PA). It is a low dropout, pulse width modulated (PWM) DC-DC converter featuring an internal low-resistance MOSFET switch and a synchronous rectifier to maximize efficiency and reduce external component requirements. The regulator supports a supply voltage range of 2.6V to 5.5V and operates across temperatures from –40°C to 85°C. It provides a programmable output voltage from 1.25V to 5.5V without the need for an external sync signal. The device has low quiescent current of approximately 180µA in skip mode and 0.1µA in shutdown. It supports 0% to 100% duty cycle operation and maintains a low dropout voltage of only 150mV at a 600mA load, including the inductor’s resistance. Applications include power management in portable devices such as cell phones, PDAs, palmtops, notebook computers, microprocessor core supplies, network cards, digital cameras, and PCMCIA cards.
