The CHP2795 is a high integrated power management IC(PMIC) with 3 DCDC buck converters and 2 LDOs.
The DCDC converters SWA and SWB supports up to 10MHz switching frequency, which provides the low ripple, fast transient power to load, with small footprint.
It features a digital interface as I2C or I3C for programmability, including output voltages, power sequences, protection threshold, etc.
A remote sensing feature is included for SWA and SWB to provide high accuracy and to support various PCB routing schemes.
Over-temperature, over-current, under-voltage and over-voltage protection features for increased system reliability are included without external sensing circuitry.
