Product details
Overview
ICE2QR2280G1XUMA1 from Infineon is a quasi-resonant AC-DC controller IC integrating an 800 V avalanche-rugged CoolMOS™ transistor in a PG-DSO-12 package, featuring active burst mode (<100 mW no-load standby), digital frequency reduction, and built-in startup cell. It targets offline SMPS in consumer adapters and auxiliary power supplies operating across 85–265 VAC input.
For engineers reviewing the ICE2QR2280G1XUMA1 datasheet, ICE2QR2280G1XUMA1 pinout, ICE2QR2280G1XUMA1 application, or ICE2QR2280G1XUMA1 equivalent, key selection criteria include VCC turn-off threshold (lower than ICE2QR2280G-1), ZC-based quasi-resonant timing, cycle-by-cycle current limiting, and integrated protection modes including latch-off OVP and auto-restart thermal/overload.
Technical Context
The device implements peak-current-mode quasi-resonant control using a digital up/down counter synchronized to transformer demagnetization via the ZC pin, enabling valley-switching down to very low loads. Its digital frequency reduction algorithm dynamically adjusts switching frequency based on feedback voltage (VFB) to minimize switching losses at light load.
Built-in protections include foldback-corrected current limiting, maximum on-time clamping, VCC under/over-voltage auto-restart, and adjustable output over-voltage latch-off triggered by ZC pin voltage monitoring - all implemented without external components beyond standard snubber and optocoupler circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 800 V - Enables direct connection to universal AC mains without external HV startup network or derating. |
| RDS(on) | 2.26 Ω @ Tj = 25°C - Sets conduction loss and thermal design baseline for ≤30 W continuous output at 50°C ambient. |
| Standby Power | <100 mW @ no load - Achieved via Active Burst Mode with controllable burst ratio and deep sleep gate drive suppression. |
| VCC Turn-off Threshold | Typ. 7.5 V - Lower than ICE2QR2280G-1 (8.5 V), enabling earlier shutdown during brownout or VCC fault conditions. |
| Soft-start Time | 12 ms (digital, 4-step) - Gradually ramps CS pin current limit from 0.32 V to 1.0 V to limit inrush stress on MOSFET, diode, and transformer. |
| Protection Modes | Auto-restart (UVP/OVP/OLP/OTP) + Latch-off (adjustable OVP, short-winding) - Dual-tier safety architecture with distinct recovery behaviors. |
Pinout & Package
Package: PG-DSO-12 (12-pin, exposed drain pad, RoHS-compliant, halogen-free mold compound).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (ZC) | Zero-Crossing Input | Detects transformer demagnetization via auxiliary winding; also serves as input for adjustable output over-voltage protection. |
| 2 (FB) | Feedback Input | Carries optocoupler-derived regulation signal; controls PWM off-time, frequency reduction, and Active Burst Mode entry/exit. |
| 3,9,10 (N.C.) | No Connect | Internally unconnected; must remain floating per datasheet - no external tie or routing. |
| 4 (CS) | Current Sense / Source | Connects to primary-side shunt resistor; enables cycle-by-cycle peak current limiting and short-winding detection during on-time. |
| 5–8 (Drain) | CoolMOS™ Drain Terminal | High-current, high-voltage power path; pins 5–8 are internally bonded to single die drain - used collectively as thermal and electrical sink. |
| 11 (VCC) | IC Supply Input | Accepts pre-charged rail from startup cell or auxiliary winding; regulated between 7.5 V (turn-off) and 25 V (OVP). |
| 12 (GND) | Power Ground | Common reference for control logic, current sense, and internal protection comparators; separate from power ground plane per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Digital Frequency Reduction | Reduces switching frequency proportionally with decreasing load via ZC-synchronized up/down counter - cuts switching loss while maintaining regulation accuracy. |
| Active Burst Mode | Suppresses gate drive and disables PWM during extended off-periods; maintains <100 mW standby with controlled output ripple and fast wake-up. |
| Built-in Startup Cell | Integrates HV startup transistor + controller to pre-charge VCC capacitor from rectified mains - eliminates external HV resistor network and associated losses. |
| Digital Soft-start | 12 ms, 4-step ramp of CS current limit threshold - prevents transformer saturation and MOSFET overstress during initial power-up. |
| Foldback Point Correction | Adjusts current limit threshold downward as VFB drops below regulation, improving overload tolerance and preventing thermal runaway at mid-load faults. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quasi-resonant AC-DC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2QR2280G-1 | VCC turn-off threshold = 8.5 V (vs. 7.5 V); otherwise identical pinout, features, and RDS(on). | Suitable where higher VCC hold-up is required to sustain operation during brief AC dips. | Select ICE2QR2280G1XUMA1 when tighter brownout response or lower VCC fault threshold is needed. |
| ICE3RBR1765J | 700 V CoolMOS™, higher RDS(on) (3.5 Ω), no built-in startup cell, requires external HV resistor. | Limited to 230 VAC-only designs; lacks Active Burst Mode - standby power >250 mW. | Choose only if cost sensitivity outweighs efficiency/standby requirements and 800 V ruggedness is unnecessary. |
Compared with ICE2QR2280G-1, ICE2QR2280G1XUMA1 offers faster brownout shutdown but identical efficiency and protection behavior; versus ICE3RBR1765J, it delivers superior universal-input capability, lower standby, and reduced BOM count at the cost of slightly higher unit price.

FAQ
What is the purpose of the ZC pin beyond zero-crossing detection?
The ZC pin serves a dual function: it provides the timing reference for valley-switching by detecting transformer demagnetization, and simultaneously acts as the input for adjustable output over-voltage protection. When VZC exceeds an internal threshold, the device enters latch-off mode - eliminating need for external OVP circuitry and reducing component count.
How does Active Burst Mode achieve sub-100 mW standby power?
Active Burst Mode reduces standby power by disabling the PWM controller and gate driver for extended periods while maintaining regulation through periodic short bursts. During each burst, the IC measures output load via FB voltage and adjusts burst interval accordingly - achieving <100 mW without sacrificing wake-up time or output stability.
Why does ICE2QR2280G1XUMA1 use multiple Drain pins (5–8)?
Pins 5–8 are electrically and thermally connected to the same CoolMOS™ drain node. Using four parallel pins lowers package inductance and improves thermal dissipation from the high-current drain path - critical for sustaining 800 V avalanche ruggedness and minimizing switching oscillation in compact layouts.
Can ICE2QR2280G1XUMA1 replace ICE2QR2280G-1 without board changes?
Yes - ICE2QR2280G1XUMA1 is a direct drop-in replacement for ICE2QR2280G-1 with identical pinout, package, and functional behavior. The only difference is the lower VCC turn-off threshold (7.5 V vs. 8.5 V), which enhances brownout response but does not affect normal operation or layout.
