CHP2780 is a high integrated power management IC(PMIC) with 5 single-phase DCDC buck converters and 7 LDOs. The LDOs can be driven by looping back the DCDC converter outputs or they can accept a separate external supply.
CHP2780 features a digital interface configurable as I2C or SPI for control of the output voltages.
A remote differential sensing feature is included for Buck1 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.
Package: WLCSP(3.69*2.69mm, 0.35mm pitch), FcCSP(5.4*5.4mm) and eSiFO(5*5mm) with 0.65mm pitch
152nm, 0.35u WLCSP ES Silicon Validated
