The MAX25250 is a high-efficiency, four-output PMIC that integrates three DC-DC converters and a high-PSRR LDO, with OV/UV monitoring on all outputs.

OUT1 is a 1A high-voltage synchronous step-down converter operating from power over coax or car battery.

OUT2 and OUT3 low-voltage synchronous step-down converters operate from OUT1 and provide a 0.8V to 3.9875V output voltage range.

a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient response. The high-frequency operation allows for the use of all ceramic capacitors and minimizes external components. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low-RDS(ON) switches improve efficiency at heavy loads and make layout simpler than discrete solutions. Sequencing through the use of EN23 and EN4 pins and factory-settable output voltages in.
