Product brief XDP digital power XDPS21071 Multi-mode, digital and configurable flyback controller The XDP digital power XDPS21071 is the first flyback controller in the industry with zero Key features voltage switching (ZVS) on the primary side to achieve high efficiency with simplified circuitry and economical switches resulting in lower BOM cost. Forced-frequency-resonant mode Self-adaptive, multi-mode operation High system efficiency with patented forced-frequency-resonant switching operation Supporting fast-charging applica- By negative magnetization, the patented forced-frequency-resonant (FFR) switching tions with variable output voltage scheme reduces the losses associated with todays valley-switching type of controllers Fixed-frequency switching without sacrificing the design simplicity of fixed-frequency switching schemes. up to 140 kHz Adaptive overcurrent protection for Ease of design and system optimization with intelligent, self-adaptive limited power supply multi-mode operation Frequency clamp at high-line input To further optimize SMPS under varying load and line input conditions, the XDPS21071 with low-output voltage comes with an intelligent, self-adaptive digital algorithm. This results in matching each UART port for configuring digital line/load condition with the best-fit operational mode (e.g., burst mode, CrCM, FFR) parameters to yield an unparalleled performance in its class. With its configurable parameters, the DSO-12 SMD package XDPS21071 serves as a scalable platform over a range of power classes - swiftly, simply and precisely. Key benefits Increase system robustness with an adaptive overcurrent protection (OCP) profile In applications where the output voltage changes according to requirements (e.g., fast High power density design with FFR charging and USB power delivery), the maximum allowable output current will be and 140 kHz switching frequency adjusted using a configurable threshold according to different output voltage settings Support LPS protection to meet to meet the limited power supply (LPS) requirement. safety regulatory requirements Light-load efficiency optimized for variable output application Fast and precise system tuning with configurable digital parameters Lead-free, RoHS compliant www.infineon.com/XDPS21071Product brief XDP digital power XDPS21071 Multi-mode, digital and configurable flyback controller Typical application schematic LFS +V OUT L F 1 DS CFS LCM RCP2 C CP COUT RX C RHV X Wp 20 V Ws CBUS 85 ... 264 VAC DCP RCP1 DVCC -VOUT RZC1 WAUX N CFV CVCC DB CZC RZC2 OptiMOS WZVS 60 V CY U1 VCC ZCD QZVS RG1 GD1 QM HV RG0 CoolMOS GPIO GD0 RFC XDPS21071 CS CFC RCS U2 MFIO CFM GND R B1 RF1 RC2 CC1 RC1 CC3 RB2 CC2 U 3 RF2 Product information Product Description Orderable part number (OPN) Package XDPS21071 FFR flyback PWM controller XDPS21071XUMA1 DSO-12 Design and support tools Type Description Ordering code Additional information REF XDPS21071 45W1 45 W USB-PD 3.0 type C charger REFXDPS2107145W1TOBO1 IF-BOARD.DP-GEN2 Gen2 .dp interface board IFBOARDDPGEN2TOBO1 www.infineon.com/dpVision GUI .dp Vision Graphical user interface software to Free download configure parameters via a PC Published by Please note Additional information Infineon Technologies Austria AG THIS DOCUMENT IS FOR INFORMATION PURPOSES ONLY AND For further information on technologies, our products, the 9500 Villach, Austria ANY INFORMATION GIVEN HEREIN SHALL IN NO EVENT BE application of our products, delivery terms and conditions REGARDED AS A WARRANTY, GUARANTEE OR DESCRIPTION OF and/or prices, please contact your nearest Infineon Technologies 2020 Infineon Technologies AG.
