PF5020 Power management integrated circuit (PMIC) for high performance applications Rev. 3 20 September 2021 Product data sheet 1 Overview The PF5020 integrates multiple high performance buck regulators. It can operate as a stand-alone point-of-load regulator IC, or as a companion chip to a larger PMIC. Built-in one-time programmable (OTP) memory stores key startup configurations, drastically reducing external components typically used to set output voltage and 2 sequence of regulators. Regulator parameters are adjustable through high-speed I C after start up offering flexibility for different system states. 2 Features Three high efficiency buck converters One linear regulator with load switch options RTC supply and coin cell charger Watchdog timer/monitor Monitoring circuit to fit ASIL B safety level One-time programmable device configuration 2 3.4 MHz I C communication interface 40-pin QFN package with wettable flank and exposed padNXP Semiconductors PF5020 Power management integrated circuit (PMIC) for high performance applications 3 Simplified application diagram VIN V1P5D V1P5A VPRE SW1IN SW1FB SW1LX SW2IN SW2FB SWND1IN SW2LX LDO1IN SWND1FB SWND1LX VDDIO LDO1OUT PF5020 PWRON STANDBY VDDIO 4 ENx VDDIO WDI PGOOD SYNC PGOODx 4 VDDIO VDDIO SDA RESETBMCU VDDIO VDDIO SCL V1P5A TBBEN INTB VDDOTP XFAILB AGND EP aaa-032546 Figure 1.Simplified application diagram 4 Ordering information Table 1.Ordering information 1 Type number Package Name Description Version 2 MPF5020CMBA0ES Plastic thermal enhanced very thin quad flat pack no leads, wettable flank, Dimple cut, 40 terminals, 0.5 mm pitch, 6 mm x 6 mm x 0.9 mm 3 MPF5020CMMA0ES body 4 MPF5020CMMACES Temperature grade: 125 C HVQFN40 SOT618-17(D) 5 MPF5020CVNA0ES Plastic thermal enhanced very thin quad flat pack no leads, wettable flank, Dimple cut, 40 terminals, 0.5 mm pitch, 6 mm x 6 mm x 0.9 mm body Temperature grade: 105 C 1 To order parts in tape and reel, add the R2 suffix to the part number. 2 Automotive part, Safety grade: ASIL B 3 Automotive part, Safety grade: QM 4 Automotive part, IMX RT1170 Reference part, Safety grade: QM 5 Industrial part PF5020 All information provided in this document is subject to legal disclaimers.
