Datasheet Summary
MAX20021/MAX20022
EVALUATION KIT AVAILABLE
Automotive Quad, Low-Voltage Step-Down DC-DC Converters
General Description
The MAX20021/MAX20022 power-management ICs (PMICs) integrate four low-voltage, high-efficiency, stepdown DC-DC converters. Each of the four outputs is factory or resistor programmable between 1.0V to 4.0V and can deliver up to 1.0A of current. The PMICs operate from 3.0V to 5.5V, making them ideal for automotive pointof-load and post-regulation applications.
The PMICs feature fixed-frequency PWM-mode operation with a switching frequency of 2.2MHz or 3.2MHz. Highfrequency operation allows for an all-ceramic capacitor design and small-size external ponents. The...
