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 (

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; 1MHz PWM switching allows for small external components, while skip mode reduces quiescent current to 180µA with light loads. The MAX1820 is dynamically controlled to provi
