ADP3210 7-Bit Programmable Multiphase Mobile CPU Synchronous Buck Controller

Pin No. Mnemonic Description 1 EN Power Supply Enable Input. Pulling this pin to GND disables the PWM outputs and pulls the PWRGD output low. 2 PWRGD Power *Good Output. Open drain output that signals when the output voltage is outside of the proper operating range. The pull

ADP3210 7-Bit, Programmable, Multiphase Mobile CPU Synchronous Buck Controller The ADP3210 is a high efficiency, multiphase, synchronous, buck switching regulator controller optimized for converting notebook battery voltage into the core supply voltage of high performance Intel processors. The part uses an internal 7 bit DAC to read Voltage Identification (VID) code directly from the processor that sets the output voltage. The phase relationship of the output signals can be confi.
