MAX25252 - Five-Output ASIL B PMIC

General Description

The MAX25252 is a high-efficiency, five-output ASIL B PMIC with three DC-DC converters, and two high-PSRR LDOs, with OV/UV monitoring on all outputs.

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

Key Features

  • temperature monitoring with external NTC. The IC accurately measures PCB temperature and flags the temperature warning through RESET. The device features a 2.1MHz fixed-frequency PWM mode for better noise immunity and load transient response. The 2.1MHz frequency operation allows for the use of all ceramic capacitors and minimizes external components. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. The I2C programmable output voltages and seque.

Five-Output ASIL B PMIC with Accurate Temperature Monitoring for Next-Generation Camera Sensors General Description The MAX25252 is a high-efficiency, five-output ASIL B PMIC with three DC-DC converters, and two high-PSRR LDOs, with OV/UV monitoring on all outputs. OUT1 is a 1A high-voltage, synchronous step-down converter operating from power over coax. OUT2 and OUT3 are low voltage synchronous step-down converters and provide a 0.75V to 3.9375V output voltage range. OUT2 and OUT3 can deliver up to 1.7A current respectively for the highmegapixel cameras and high-speed serializers. LDO4 and LDO5 deliver up to 0.4A and 0.9A of current to power the secondary rails of the imager and a serializer.
