Product details
Overview
XDPS21061XUMA1 from Infineon Technologies is a digitally controlled AC-DC primary-side controller IC for high-efficiency, low-standby-power offline SMPS in 85–265 VAC applications. It integrates a 650 V CoolMOS™ P7 power transistor, supports quasi-resonant (QR) and DC/DC flyback operation, delivers up to 65 W output power, and achieves <30 mW no-load consumption per IEC 62301 Ed. 2.0.
For engineers reviewing the XDPS21061XUMA1 datasheet, XDPS21061XUMA1 pinout, XDPS21061XUMA1 application, or XDPS21061XUMA1 equivalent, key selection criteria include integrated high-voltage MOSFET rating, QR zero-voltage switching (ZVS) capability, digital adaptive burst-mode control for ultra-low standby, and compliance with DOE Level VI and CoC v5 efficiency standards.
Technical Context
The XDPS21061XUMA1 implements a digital state-machine-based controller with real-time adaptive QR timing control, enabling precise valley-switching across line and load variations. It embeds a 650 V, 0.4 Ω CoolMOS™ P7 superjunction MOSFET and supports primary-side regulation without optocoupler feedback.
Its digital core executes programmable soft-start, overvoltage protection (OVP), overtemperature protection (OTP), and cycle-by-cycle current limiting. The device operates in discontinuous conduction mode (DCM) with variable switching frequency up to 130 kHz and features built-in brown-in/brown-out detection with hysteresis.

FAQ
What is the maximum continuous output power supported by XDPS21061XUMA1?
XDPS21061XUMA1 supports up to 65 W continuous output power at 230 VAC input with standard PCB layout and natural convection cooling. Derating to 55 W is recommended at 115 VAC full-load due to higher RMS current stress on the integrated MOSFET.
Does XDPS21061XUMA1 require an external optocoupler for regulation?
No. XDPS21061XUMA1 implements primary-side regulation (PSR) using auxiliary winding voltage sampling at the FB pin. This eliminates the need for optocoupler, TL431, and secondary-side feedback circuitry, reducing BOM cost and improving system reliability.
Can XDPS21061XUMA1 operate in continuous conduction mode (CCM)?
No. XDPS21061XUMA1 is optimized for discontinuous conduction mode (DCM) and quasi-resonant (QR) operation only. Its digital control engine detects valley points in DCM and does not support CCM timing or control loops.
What thermal management considerations apply to the PG-DSO-12 package?
The PG-DSO-12 package features an exposed thermal pad that must be soldered to a minimum 100 mm² copper pour connected to internal ground planes. Thermal resistance from junction-to-board is 32 °C/W; board-level airflow ≥1 m/s reduces θJA to 24 °C/W for 65 W operation.
