The MAX20002/MAX20003 are small, synchronous buck converters with integrated high-side and low-side MOSFETs. Each device is designed to deliver up to 2A/3A with input voltages from 3.5V to 36V, while using only 15µA quiescent current at no load. Voltage quality can be monitored by observing the PGOOD signal. The devices can operate in dropout by running at 98% duty cycle, making them ideal for automotive applications.

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.
