It accepts a 3.5 V to 36 V input and delivers up to 3 A output with a programmable fixed voltage of 1 V or 3.3 V. The switching frequency is adjustable from 220 kHz to 2.2 MHz, allowing the designer to trade off inductor size against efficiency. Synchronous rectification is built in, so no external Schottky diode is needed for the low-side switch. ## Temperature grade and package fit The 3 A continuous rating covers most automotive sensor and MCU supply rails; derating at elevated temperature follows the package's RθJA curve.","metaTitle":"MAX20003CATPB/V+ Buck Converter, 3A, 20-TQFN","metaDescription":"Active-production Analog Devices MAX20003CATPB/V+ step-down buck converter, 3.5-36V input, 3A output, AEC-Q100, -40 to 125°C.
