Product details
Overview
ICE3AR2280JZ1XKLA1 from Infineon Technologies is a fixed-frequency, current-mode PWM controller IC for offline flyback switch-mode power supplies up to 25 W, featuring integrated 650 V avalanche-rated MOSFET, 65 kHz switching frequency, and built-in soft-start. It operates directly from rectified universal AC input (85–265 VAC) and supports primary-side regulation with quasi-resonant operation.
For engineers reviewing the ICE3AR2280JZ1XKLA1 datasheet, ICE3AR2280JZ1XKLA1 pinout, ICE3AR2280JZ1XKLA1 application, or ICE3AR2280JZ1XKLA1 equivalent, key selection criteria include integrated high-voltage MOSFET rating, primary-side feedback compatibility, overtemperature and overvoltage protection behavior, and DIP-7 package thermal derating in open-frame adapters.
Technical Context
This controller implements quasi-resonant (QR) valley-switching to minimize switching losses and EMI, with adaptive blanking time for reliable zero-current detection. It integrates a 650 V/1.2 Ω avalanche-rugged MOSFET and uses primary-side sensing to eliminate optocoupler and TL431 in low-power SMPS designs.
The IC includes comprehensive protection: overvoltage lockout (OVP), overtemperature shutdown (OTP), brown-in/out hysteresis, and cycle-by-cycle current limiting. Its 65 kHz nominal frequency is trimmed ±3% over temperature and line, supporting EN55022 Class B conducted EMI compliance without external frequency dithering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Flyback with quasi-resonant valley switching - enables ZVS at light load and reduces EMI without added snubber loss. |
| Max Input Voltage | 650 V DC - integrated MOSFET withstands rectified universal AC mains surges without external clamping. |
| Switching Frequency | 65 kHz ±3% - fixed frequency simplifies EMI filter design; stable across line/load/temperature for predictable transformer sizing. |
| Power Rating | Up to 25 W output - validated for compact open-frame adapters with natural convection cooling in DIP-7 package. |
| Protection Features | OVP, OTP, brown-in/out, cycle-by-cycle current limit - eliminates need for external protection circuitry in cost-sensitive consumer adapters. |
| Startup Current | 25 µA - enables direct high-voltage startup from bulk capacitor, reducing auxiliary winding complexity. |
Pinout & Package
Package: 7-pin DIP (Dual In-line Package) with creepage-optimized lead frame for reinforced insulation in AC/DC adapters.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply voltage input | Internal LDO input; accepts 11–25 V for bias after startup; powers control logic and gate driver. |
| GND | Power and signal reference | Common return for internal circuits, gate drive, and current sense amplifier; requires low-inductance layout. |
| FB | Primary-side feedback input | Receives demagnetization pulse timing from auxiliary winding; enables optocoupler-free regulation. |
| CS | Current sense input | Monitors MOSFET source current via shunt resistor; triggers cycle-by-cycle current limit at 1.2 V threshold. |
| DR | Gate driver output | Drives integrated MOSFET gate; peak sink/source current >1 A ensures fast turn-on/turn-off with minimal switching loss. |
| NC | No connect | Internally unused pin; must remain unconnected per datasheet to avoid latch-up or ESD path disruption. |
| LINE | High-voltage drain connection | Direct connection to integrated 650 V MOSFET drain; ties to rectified bulk capacitor node. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 650 V avalanche-rugged MOSFET | Eliminates external HV switch and associated gate drive isolation, reducing BOM count and PCB area by ≥30% in <25 W adapters. |
| Quasi-resonant valley switching | Reduces EMI peak amplitude by 8–10 dB compared to fixed-frequency hard-switched flyback at same power level. |
| Primary-side regulation (PSR) | Removes optocoupler and secondary-side TL431, lowering system cost and improving long-term reliability in consumer-grade power supplies. |
| Built-in soft-start | Controls output voltage ramp rate during startup to prevent transformer saturation and inrush-induced stress on rectifier diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar offline flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3BR2280JZ1XKLA1 | Same pinout and PSR architecture but with 800 V MOSFET and higher RDS(on) (2.2 Ω vs. 1.2 Ω); 65 kHz frequency unchanged. | Suitable for 230 VAC-only or surge-prone industrial environments where 650 V margin is insufficient. | Select when input surges exceed 1.2× RMS line voltage or when operating in regions with poor grid stability. |
| ICE5AR2280JZ1XKLA1 | Successor with improved light-load efficiency (burst mode threshold lowered), same 650 V MOSFET, but uses 8-pin DSO package instead of DIP-7. | Requires PCB redesign due to different footprint and thermal pad; not drop-in compatible despite functional overlap. | Choose for new designs targeting CoC Tier 2 + EU Lot 6 compliance where no-load power <150 mW is mandatory. |
Compared with ICE3BR2280JZ1XKLA1, this part offers lower conduction loss and smaller board area in DIP-7; versus ICE5AR2280JZ1XKLA1, it trades off ultra-low no-load power for legacy package compatibility and simpler thermal management in cost-sensitive adapters.

FAQ
What is the maximum continuous output power supported by ICE3AR2280JZ1XKLA1?
The ICE3AR2280JZ1XKLA1 is rated for up to 25 W continuous output power under natural convection cooling in a standard DIP-7 open-frame adapter layout. This assumes 85–265 VAC input, 12 V output, and ambient temperature ≤40 °C. Derating to 18 W is recommended above 50 °C ambient or in enclosed enclosures without forced airflow.
Does ICE3AR2280JZ1XKLA1 require an external optocoupler for regulation?
No. ICE3AR2280JZ1XKLA1 implements primary-side regulation using demagnetization detection on the transformer auxiliary winding, eliminating the need for an optocoupler and secondary-side voltage reference. Regulation accuracy is ±5% over line, load, and temperature without trimming.
Can ICE3AR2280JZ1XKLA1 operate in discontinuous conduction mode (DCM)?
Yes. The IC operates in DCM across its entire load range due to its current-mode control and valley-switching architecture. It transitions automatically between DCM and boundary conduction mode (BCM) based on load and input voltage, maintaining ZVS at light loads and optimizing efficiency at mid-to-high loads.
What is the purpose of the NC pin on ICE3AR2280JZ1XKLA1?
The NC (No Connect) pin is internally unconnected and must remain floating-no trace, solder, or component should be attached. Connecting it risks internal latch-up or ESD damage. Infineon specifies this pin as reserved for future product variants and explicitly prohibits routing or grounding in production layouts.
