Product details
Overview
ICE2QR2280ZXKLA1 from Infineon Technologies is a quasi-resonant AC-DC PWM controller IC with integrated 800V avalanche-rugged CoolMOS® and startup cell in PG-DIP-7 package. It delivers 54W at 230VAC ±15% with typ. RDS(on) = 2.26Ω, operates across 85–265VAC input, and enables active burst mode for <100mW no-load standby power - deployed in LCD monitors, Blu-ray DVD players, and set-top boxes.
For engineers reviewing the ICE2QR2280ZXKLA1 datasheet, ICE2QR2280ZXKLA1 pinout, ICE2QR2280ZXKLA1 application, or ICE2QR2280ZXKLA1 equivalent, key selection criteria include integrated high-voltage MOSFET rating, quasi-resonant zero-crossing detection timing, digital frequency reduction behavior under light load, active burst mode control logic, and VCC pre-charge startup sequence compliance.
Technical Context
The ICE2QR2280ZXKLA1 implements peak-current-mode quasi-resonant control using a digital up/down counter synchronized to transformer demagnetization via ZC pin input. Its internal CoolMOS® drain connects directly to the primary winding, enabling self-biased startup through an integrated high-voltage current source that charges VCC to 14.5V before enabling soft-start.
Digital frequency reduction adjusts switching frequency downward as load decreases - governed by feedback voltage (VFB) thresholds (VFBZL, VFBZH, VFBR1) sampled every 48ms - while active burst mode disables PWM cycles entirely below ~5% load, reducing average switching loss and achieving <0.1W input power at no load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 800V - supports universal AC input (85–265VAC) without external HV starter or snubber clamp |
| RDS(on) | 2.26Ω @ Tj = 25°C - enables 54W continuous output at 230VAC with minimal conduction loss |
| Startup Cell | Integrated HV current source - provides ~1.05mA constant-current VCC pre-charge until 14.5V turn-on threshold |
| Active Burst Mode | Enables <100mW no-load input power - eliminates audible noise and reduces standby energy consumption |
| Digital Soft-Start | 12ms, 4-step ramp - limits inrush current and controls peak CS voltage from 0.32V to 1.0V linearly |
| Zero-Crossing Detection | Digital ZC counter with ringing suppression - ensures MOSFET turn-on only at valley points, minimizing EMI and voltage stress |
| Protections | Auto-restart for VCC OVP/UVP, overload, overtemperature; latch-off for adjustable OVP and short-winding fault |
Pinout & Package
Package: PG-DIP-7 (Plastic Dual-In-Line Package, 7-pin, wide-body, creepage-optimized for 800V isolation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - ZC | Zero-Crossing Input | Accepts delayed auxiliary winding signal; triggers valley-switching and enables OVP detection via internal threshold comparison |
| 2 - FB | Feedback Input | Carries optocoupler-derived regulation signal; controls PWM off-time, digital frequency reduction, and burst mode entry/exit |
| 3 - CS | Current Sense Input | Monitors primary-side shunt resistor voltage; enables cycle-by-cycle peak current limiting and short-winding protection |
| 4 - N.C. | No Connection | Internally unconnected; must remain floating - no external tie or pull-up/pull-down |
| 5 - Drain | CoolMOS® Drain Terminal | High-side switch node connected directly to primary winding; rated for 800V avalanche energy handling |
| 6 - - | No Pin | Physical gap in DIP-7 footprint; no metallization or internal connection |
| 7 - VCC | Controller Supply | Receives pre-charged and auxiliary-winding-derived bias; operates 9.5–25V with auto-restart on OVP/UVP |
| 8 - GND | Controller Ground | Reference for all analog comparators and digital logic; tied to source of internal CoolMOS® |
Key Features
| Feature | Design Value |
|---|---|
| Quasi-resonant valley switching | Reduces EMI and secondary diode voltage stress by synchronizing MOSFET turn-on to transformer demagnetization minima |
| Digital frequency reduction | Lowers switching frequency progressively as load drops - maintains efficiency >75% down to 10% load without burst artifacts |
| Built-in startup cell | Eliminates external HV start-up resistor network - reduces BOM count and improves reliability over discrete solutions |
| Foldback point correction | Adjusts current limit threshold dynamically with line voltage - ensures consistent power delivery across 85–265VAC range |
| Auto-restart protections | Recovers automatically from overtemperature, overload, and VCC faults - avoids latching shutdown during transient conditions |

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 |
|---|---|---|---|
| ICE2QR4780Z | Higher RDS(on) = 4.7Ω; same 800V rating and pinout; lower max. output power (31W vs. 54W) | Suitable for sub-30W applications where thermal margin allows higher conduction loss | Select when BOM cost sensitivity outweighs efficiency targets and board space permits larger heatsinking |
| ICE3B0565J | Fixed-frequency PWM (not QR); 650V CoolMOS®, no integrated startup cell; requires external HV resistor | Used in cost-sensitive, non-EMI-critical designs where valley switching is not required | Choose only if design already uses fixed-frequency topology and can accommodate external startup network |
Compared with ICE2QR4780Z and ICE3B0565J, ICE2QR2280ZXKLA1 uniquely combines 800V integration, valley-switching control, and autonomous startup - delivering highest power density and lowest no-load consumption in its class without external HV components.

FAQ
What is the maximum continuous output power supported by ICE2QR2280ZXKLA1?
At 230VAC ±15% input with 232mm², 2 oz copper area on the Drain pin acting as heatsink, ICE2QR2280ZXKLA1 supports 54W continuous output power. At 115VAC, derating applies due to higher RMS current; maximum usable power drops to 31W under identical thermal conditions per Infineon's published input power curve.
Does ICE2QR2280ZXKLA1 require an external high-voltage startup resistor?
No. ICE2QR2280ZXKLA1 integrates a dedicated startup cell within the CoolMOS® structure that delivers ~1.05mA constant-current charging to the VCC capacitor until the 14.5V turn-on threshold is reached - eliminating the need for external HV resistors and associated power loss and reliability concerns.
How does the active burst mode reduce no-load power consumption?
Under light load, ICE2QR2280ZXKLA1 enters active burst mode by disabling entire PWM switching cycles while maintaining regulation via periodic sampling of FB voltage. This reduces average switching loss and gate drive power, achieving <100mW input power at no load - verified per IEC 62301 Ed.2 test conditions.
Can ICE2QR2280ZXKLA1 be used in 240VAC-only industrial applications?
Yes. Though optimized for universal 85–265VAC input, ICE2QR2280ZXKLA1's 800V CoolMOS® drain rating and foldback point correction ensure robust operation at 240VAC nominal with full protection functionality active - including VCC OVP, overtemperature, and overload auto-restart modes.
