MAX1820 Datasheet Wcdma Cellular Phone 600ma Buck Regulators

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2011; Rev 2; 7/02 KIT ATION EVALU E L .. B AVAILA WCDMA Cellular Phone 600mA Buck.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX1820/MAX1821 low-dropout, pulse-width-modulated (PWM) DC-DC buck regulators are optimized to provide power to the power amplifier (PA) in WCDMA cell phones;

however, they may be applied in many other applications where high efficiency is a priority.

The supply voltage range is from 2.6V to 5.5V, and the guaranteed output current is 600mA;

Key Features

  • o Dynamically Adjustable Output from 0.4V to 3.4V (MAX1820) o Programmable Output from 1.25V to 5.5V (MAX1821) o SYNC to 13MHz External Clock (MAX1820X) o SYNC to 19.8MHz External Clock (MAX1820Y) o NO SYNC, Internal 1MHz Oscillator (MAX1820Z) o Low Quiescent Current 180µA (typ) in Skip Mode 0.1µA (typ) in Shutdown Mode o No External Schottky Diode Required o 600mA Guaranteed Output Current o 0% to 100% Duty-Cycle Operation o 150mV Dropout at 600mA Load (Including RDC of External Inductor) o µMA.
