MAX25252 Overview
Key Specifications
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 sequencing increases flexibility for different image sensors and configurations
- Other features include soft-start, overcurrent, and overtemperature protections
