Analog Devices / Maxim Integrated MAX20419EVKIT PMIC Evaluation Kit

Analog Devices Inc. MAX20419EVKIT PMIC Evaluation Kit is a fully assembled and tested PCB that demonstrates the MAX20419ATGB/V+ power-management IC (PMIC). The evaluation kit includes three high-efficiency, low-voltage DC-DC converters. The OUT1 boosts a 3.3V input to 5V at up to 750mA. The two synchronous step-down converters (OUT2, OUT3) provide output voltages of 2.3V and 1.25V up to 2A. The 2.2MHz switching-frequency operation allows for the use of all-ceramic capacitors and minimizes external components. The evaluation kit features three on/off jumper controls, and three reset outputs to indicate output status for each converter. The evaluation kit provides a SYNC input to select the operating mode (PWM, skip, or external synchronization). The evaluation kit also provides an open-drain power-good output (active-low PV_OV) that asserts when the input supply voltage is 3.7% above or below the target input voltage.
