Product details
Overview
XDPS2201XUMA1 from Infineon Technologies is a digital hybrid-flyback controller with integrated half-bridge driver in DSO-14 (150mil) package, designed for high-density AC/DC SMPS. It delivers zero-voltage switching (ZVS), supports <75 mW no-load standby power, employs peak current mode control, and enables burst mode operation via output current estimation.
For engineers reviewing the XDPS2201XUMA1 datasheet, XDPS2201XUMA1 pinout, XDPS2201XUMA1 application, or XDPS2201XUMA1 equivalent, key selection considerations include ZVS capability across wide input/output voltage ranges, configurable dual-level overcurrent protection, UART-based parameter tuning, and industrial qualification per JEDEC47/20/22.
Technical Context
The XDPS2201 implements asymmetrical half-bridge control driving a conventional flyback transformer with a series capacitor to form a resonant tank-enabling ZVS of power switches and resonant power transfer during demagnetization. Its CRM operation ensures robust line/load regulation via direct peak current control, while timing-controlled demagnetization guarantees negative premagnetization for reliable ZVS initiation.
ZV-RVS and burst modes extend efficiency across full load range; propagation delay compensation (PDC) ensures accurate current sensing; and one-pin UART allows in-circuit calibration of brown-in/out thresholds, soft-start, OVP, frequency jitter, and cycle-skipping behavior without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hybrid-flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28780 | TI's active-clamp flyback controller; lacks integrated half-bridge driver and ZVS resonant tank support | Requires external high/low-side drivers and discrete resonant components; higher BOM count | Preferred when active-clamp topology is mandated and ZVS optimization is secondary to cost |
| ICE5QSBG | Infineon's quasi-resonant flyback controller; no half-bridge integration, no UART configuration, fixed burst thresholds | Relies on optocoupler feedback and discrete gate drivers; limited configurability for EMI tuning | Selected for cost-sensitive, lower-power (<30 W) designs where ZVS and in-field calibration are not required |
Compared with UCC28780 and ICE5QSBG, XDPS2201XUMA1 uniquely integrates a half-bridge driver and resonant control logic to achieve ZVS without external timing components, supports real-time UART calibration for EMI and efficiency optimization, and delivers lowest standby power in its class-making it optimal for ultra-dense, high-efficiency adapters above 45 W.

FAQ
What is the purpose of the MFIO pin on XDPS2201XUMA1?
The MFIO pin serves as a single-wire UART interface for configuring and calibrating over 30 parameters-including burst mode thresholds, soft-start duration, OVP level, and frequency jitter-without requiring additional communication hardware. It enables in-circuit tuning during production or field deployment, reducing design iteration cycles and supporting firmware updates via standard UART tools.
How does XDPS2201XUMA1 achieve zero-voltage switching (ZVS)?
XDPS2201XUMA1 achieves ZVS by controlling an asymmetrical half-bridge that drives a flyback transformer in series with a capacitor, forming a resonant tank. The IC precisely times the demagnetization phase to ensure negative premagnetization before each switching cycle, allowing the high- and low-side MOSFETs to turn on at near-zero voltage-verified across 85–264 VAC input and 5–24 V output ranges per JEDEC validation reports.
Does XDPS2201XUMA1 require an optocoupler for feedback?
No-XDPS2201XUMA1 supports primary-side regulation using the FB pin to monitor reflected output voltage, eliminating the need for an optocoupler or secondary-side TL431 shunt regulator. This reduces component count, improves reliability, and simplifies transformer design while maintaining ±3% output voltage accuracy across line, load, and temperature per datasheet test data.
What protection features are implemented in hardware versus firmware?
Hardware protections include VCC undervoltage lockout (UVOFF), HSVCC UVOFF, CS short-circuit detection, and start-up timeout (STTOP)-all implemented in analog circuitry with sub-microsecond response. Firmware-managed protections-such as burst mode exit timing, OCP1 level transitions, and watchdog reset-are executed by the embedded digital controller with configurable latency via UART, ensuring both speed and flexibility.
