MAX20003CATPB/V+

The MAX20003CATPB/V+ is a 36V, 220KHz to 2.2MHz, 3A fully integrated step-down converter with 15µA operating current in 20 pin TQFN-EP package. It is a small, synchronous buck converter with integrated high-side and low-side MOSFETs. Each device is designed to deliver up to 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 PGOOD signal. It operates in dropout by running at 98% duty cycle, making it ideal for automotive applications. The device offers fixed output voltage of 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. It offers a forced fixed-frequency mode and skip mode. It has a pin that can be programmed to turn on/off the spread spectrum, further helping systems designers with better EMC management.
