Additional Infomation About Product

PV88080 High Efficiency Advanced Feature 4-Channel PMIC General Description The PV88080 power management integrated circuit (PMIC) provides one PWM buck controller and three adjustable synchronous buck regulators. The high voltage buck controller can optionally be used to generate the supply for the other three buck converters. Two pass devices (NMOS FET) for the high side and low side of the high voltage buck controller are external which allows the majority of the buck controller power dissipation to be outside the PV88080. This high voltage buck controller uses a constant on time (COT) control scheme with integrated bootstrap PMOS switch. In certain applications, multiple PV88080s can be used together to provide enough power rails to power the larger systems. There are three buck converters that can be used to generate the supplies for CPUs, DDR memory and other Auxiliary functions in a typical application. The pass devices of these buck converters are fully integrated, so no external FETs or Schottky diodes are needed. This results in optimized power efficiency and a reduced external component count. PV88080 provides Dynamic Voltage Control (DVC) via I2C command to support adaptive adjustment of the supply voltage based on the processor. All power blocks have over current circuit protection and the start-up timing can be 2 controlled through the I C interface. Soft start-up limits the inrush current from the input node and secures a slope controlled activation of the rail. The PV88080 is available in a 32-pin QFN package and is specified from 40 C to 85 C ambient temperature. Key Features One synchronous buck controller Light load efficiency improved > 85% VIN input voltage range : 7 V to 26 V Boot up selectable output voltage through GPIO Programmable output voltage : 0.8 V~5.25 V when VIN <13.2 V or Dynamic Voltage Control (DVC) on all buck 1.8 V~5.25 V when V >13.2 V converters IN Supports all ceramic output capacitors Constant on time (COT) control with selectable frequencies Switching frequency up to 1 Mhz Auto mode on all three buck converters Reference voltage with 1% tolerance Adjustable soft start Provide OVP, OCP and OTP 2 Two GPIO, one nIRQ and I C compatible Three synchronous buck converters with interface integrated low RON FET Mute function: eliminates audio popping Buck1, programmable output voltage from noise in power plug OFF scenario. 0.75 V to 3.3 V with 5-A continuous output current. Peak current 6 A if standalone. Power fail detect function to alert the application processor.

Peak current 3 A if standalone. the remote temperature sensing ability on the system. Buck3, programmable output voltage from 0.9 V to 3.6 V with 2-A continuous output -40 to 85 C ambient temperature range current. Peak current 3 A if standalone.
