Description
The devices offer fixed output voltages of 5V/3.3V, along with the ability to program the output voltage between 1V to 10V. Frequency can be programmed using a resistor to ground on the FOSC pin from 220kHz to 2.2MHz. The devices offer a forced fixed-frequency mode and skip mode with ultra-low quiescent current of 15µA. They have a pin that can be programmed to turn on/off the spread spectrum, further helping systems designers with better EMC management.
The MAX20002/MAX20003 are available in a small 5mm x 5mm 20-pin TQFN package with exposed pad and use very few external components.
