MAX1820 regulators equivalent, wcdma cellular phone 600ma buck regulators.
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.
where high efficiency is a priority. The supply voltage range is from 2.6V to 5.5V, and the guaranteed output current is.
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 pri.
