Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20021ATIA/V power management IC (PMIC) integrates four low-voltage, high-efficiency, step-down DC-DC converters, each of which is factory-programmable from 1.0V to 4.0V and can deliver up to 1A of current. Each of the four outputs is factory or resistor programmable from 1.0 V to 4.0 V and can deliver up to 1.0 A. The PMICs operate from 3.0 V to 5.5 V, making them ideal for automotive point-of-load and post regulation applications.

The MAX20021ATIA/V PMIC is available in a 28-pin TQFN package with exposed pads and is specified for operation over the automotive temperature range of -40ºC to +125ºC.
