Product details
Overview
ICE5QR2270AZXKLA1 from Infineon is a quasi-resonant 700 V integrated power IC combining a controller and avalanche-rugged CoolMOS™ in a single DIP-7 package. It delivers up to 41 W at 220 VAC ±20% and 22 W across 85–300 VAC, supports digital frequency reduction up to 10 zero crossings, achieves <100 mW standby power via enhanced Active Burst Mode, and targets auxiliary power supplies in home appliances and LCD/LED monitors.
For engineers reviewing the ICE5QR2270AZXKLA1 datasheet, ICE5QR2270AZXKLA1 pinout, ICE5QR2270AZXKLA1 application, or ICE5QR2270AZXKLA1 equivalent, key selection criteria include its 700 V drain rating, 2.13 Ω RDS(on), cascode-based fast startup, robust line protection (OVP/brownout), and digital soft-start implementation.
Technical Context
This IC implements a current-mode PWM controller with integrated 700 V CoolMOS™ in cascode configuration, enabling quasi-resonant flyback operation with zero-crossing detection (ZCD) and digital frequency reduction logic. Its dual-line sensing on VIN pin sets minimum ZC count for low/high AC input, reducing EMI while maintaining efficiency across universal input ranges.
The device integrates cycle-by-cycle peak current limiting, programmable burst entry/exit thresholds via FB pin, auto-restart protection for VCC OVP/UVP, overtemperature, output OVP, CS short-to-GND, and built-in soft-start with 50 µs blanking time. All protections trigger autorestart with configurable hysteresis.
Key Specifications

Pinout & Package
ICE5QR2270AZXKLA1 is housed in PG-DIP-7 (7-pin dual in-line plastic) package with creepage/clearance optimized for reinforced insulation in offline applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback & Burst Control | Accepts optocoupler feedback voltage; sets burst entry/exit thresholds and triggers overload/open-loop protection. |
| 2 VIN | Line Voltage Sense | Connects to resistor divider on bulk rail; enables input OVP, brownout detection, and adaptive ZC count selection. |
| 3 CS | Current Sense Input | Receives primary-side shunt voltage; determines switch-off timing and detects CS short-to-GND fault. |
| 4 ZCD | Zero-Crossing Detection | Monitors transformer auxiliary winding; initiates startup charging of VCC and provides output OVP detection. |
| 5–7 DRAIN | High-Voltage Drain Node | Internally connects to CoolMOS™ drain; carries full primary-switching current and high-voltage stress. |
| 7 VCC | IC Supply Input | Provides regulated bias to internal circuitry; monitored for OVP (16 V) and UVP (10 V) with autorestart. |
| 8 GND | Power Ground Reference | Common return path for control logic, current sense, and gate driver; isolated from high-side drain node. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 700 V CoolMOS™ | Eliminates external HV MOSFET and associated gate drive complexity in flyback auxiliary supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quasi-resonant flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE5QR2270AG | Same silicon die but in PG-DSO-12 package; includes two NC pins and separate GND/VIN routing. | Requires PCB redesign for surface-mount assembly; better thermal dissipation at >30 W continuous load. | Select for SMT production or higher thermal performance; avoid if through-hole mounting or legacy DIP footprint required. |
| ICE5QR1070AZ | 700 V, 1.15 Ω RDS(on); rated for 58 W at 220 VAC-higher conduction loss at light load due to lower frequency reduction depth. | Suitable for higher-output auxiliary supplies where <100 mW standby is less critical than peak power capability. | Choose when output power demand exceeds 41 W but design can tolerate ~150 mW standby and reduced ZC flexibility. |
Compared with ICE5QR2270AG, ICE5QR2270AZXKLA1 offers identical electrical specs but simplified through-hole assembly and lower layout complexity; versus ICE5QR1070AZ, it trades peak power headroom for superior light-load efficiency and tighter standby control-ideal for cost-sensitive, energy-regulated consumer electronics.

FAQ
What is the maximum continuous output power supported by ICE5QR2270AZXKLA1?
At 220 VAC ±20%, ICE5QR2270AZXKLA1 supports up to 41 W in open-frame design with 2 oz copper PCB and Ta = 50°C. At universal input (85–300 VAC), maximum output is 22 W. Actual power depends on transformer design, heatsinking, and ambient conditions-designers should validate with Infineon's ICE5QR2270AZ reference schematics and thermal models.
How does the VIN pin implement both brownout and input OVP protection?
The VIN pin uses a single resistor divider to sense bulk DC voltage. Internal comparators monitor this node against two thresholds: ~150 V for brownout (UVLO) and ~450 V for OVP. Each function has dedicated 250 µs blanking timers to reject transients, and both trigger autorestart with hysteresis-no external components are needed beyond the divider network.
Can ICE5QR2270AZXKLA1 operate without an optocoupler in the feedback loop?
No-it requires optocoupler-based feedback via the FB pin for primary-side regulation and burst mode control. The FB pin senses reflected output voltage and sets burst entry/exit thresholds using external resistors. Secondary-side shunt regulators (e.g., TL431) with optocouplers are mandatory for stable cross-regulation and safety isolation.
What is the purpose of the ZCD pin beyond zero-crossing detection?
ZCD serves three roles: (1) During startup, it provides initial gate drive to charge the VCC capacitor via the auxiliary winding; (2) In normal operation, it detects transformer demagnetization for QR timing; (3) It monitors auxiliary winding voltage for output overvoltage protection-exceeding internal threshold triggers immediate shutdown and autorestart.
