Product Details

The MAX20419 evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the MAX20419ATGB/V+ power-management IC (PMIC). The EV kit includes three high-efficiency, low-voltage DC-DC converters: OUT1 boosts a 3.3V input to 5V at up to 750mA, while 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 EV kit features three on/off jumper controls and three reset outputs to indicate output status for each converter. The EV kit also provides a SYNC input to select the operating mode (PWM, skip, or external synchronization), and 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.
