Product details
Overview
ICE3A2065ZXKLA1 from Infineon Technologies is a fully integrated off-line SMPS current-mode controller with built-in 650V depletion-mode CoolMOS™ and startup cell, housed in PG-DIP-7-1 package. It delivers 57W input power at 230VAC ±15%, operates at fixed 100kHz switching frequency, features active burst mode for <100mW standby power, and targets AC/DC flyback converters in consumer power adapters.
For engineers reviewing the ICE3A2065ZXKLA1 datasheet, ICE3A2065ZXKLA1 pinout, ICE3A2065ZXKLA1 application, or ICE3A2065ZXKLA1 equivalent, key selection criteria include its integrated high-voltage switch, precise ±5% peak current limiting, adjustable blanking window for load-jump immunity, and Auto Restart protection modes for overtemperature, overvoltage, overload, and VCC undervoltage.
Technical Context
The ICE3A2065ZXKLA1 implements a current-mode PWM control architecture with internal oscillator set to 100kHz, leading-edge blanking, and propagation delay compensation for accurate current sensing. Its integrated 650V CoolMOS™ enables direct rectified AC line connection without external HV startup resistor.
Control logic includes an Active Burst Mode triggered by feedback voltage level, delivering immediate response to load transients while maintaining <1% output ripple. Protection is implemented via Auto Restart Mode across five fault conditions-overtemperature, VCC overvoltage, open-loop, overload, and VCC undervoltage-with no latch-off behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650V rated drain-source voltage - supports direct connection to 265VAC rectified input without external HV startup network |
| fSW | 100kHz fixed switching frequency - enables compact transformer design and predictable EMI profile |
| RDS(on) | 0.92Ω @ Tj = 25°C - enables 57W continuous input power at 230VAC in open-frame DIP-7 layout |
| ICLIM tolerance | ±5% overall peak current limit accuracy - reduces transformer and secondary diode sizing margin, lowering BOM cost |
| Standby power | <100mW at no load - meets stringent global energy efficiency standards (e.g., DOE Level VI, CoC Tier 2) |
| Blanking window | Adjustable - prevents false triggering of current limit during high di/dt events like load jumps |
| Duty cycle max | 72% - provides sufficient headroom for transient response and transformer reset in discontinuous conduction mode |
Pinout & Package
ICE3A2065ZXKLA1 uses the PG-DIP-7-1 package: 7-pin dual-in-line with gull-wing leads, RoHS-compliant lead plating, and creepage distance optimized for 265VAC mains isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SoftS | Soft-start timing node - external capacitor sets ramp-up time for controlled VOUT rise and inrush current limiting |
| 2 | FB | Feedback input - connects to optocoupler cathode to regulate output voltage via error amplifier and PWM duty adjustment |
| 3 | CS | Current sense input - monitors CoolMOS™ source voltage to implement precise peak current mode control and OCP |
| 4 | n.c. | No connect - internally unconnected; must remain floating per datasheet |
| 5 | Drain | Main power switch drain - connects directly to primary winding of flyback transformer and rectified AC input |
| 7 | VCC | Controller supply - powered after startup via auxiliary winding; regulated internally to 14.6V typical |
| 8 | GND | Controller ground reference - common return for FB, CS, SoftS, and internal logic; separate from power ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 650V CoolMOS™ + controller | Eliminates external HV startup resistor and gate driver, reducing component count by ≥4 and PCB area by ~25% |
| Active Burst Mode | Delivers immediate load-step response with no output blackout, unlike traditional burst modes that disable controller between cycles |
| Precise peak current limiting | ±5% tolerance enables tighter transformer turns ratio design and smaller secondary rectifier selection |
| Auto Restart protection suite | Five independent fault detection paths (OTP, OVP, OLP, OL, UVLO) reset automatically after fault clearance - no manual intervention required |
| Adjustable blanking window | Configurable via external RC on SoftS pin to suppress false current-limit triggers during fast load transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line SMPS controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3A2065Z | Same die, identical electrical specs, PG-DIP-7-1 package - ICE3A2065ZXKLA1 is the full-orderable part number including packaging and traceability codes | No functional difference; XKL A1 suffix denotes tape-and-reel packaging and full Infineon logistics traceability | Select ICE3A2065ZXKLA1 for production volume orders requiring full lot traceability and JEDEC-compliant packaging |
| ICE3B2065Z | Same RDS(on) and power rating but 67kHz switching frequency - lower EMI but requires larger magnetics | Better suited for noise-sensitive environments (e.g., audio equipment), less optimal for space-constrained adapters | Choose ICE3B2065Z only when EMI filtering constraints outweigh size/cost targets |
Compared with ICE3A2065Z, ICE3A2065ZXKLA1 offers identical performance with certified logistics packaging; versus ICE3B2065Z, it trades higher-frequency operation (100kHz) for smaller transformers and faster transient response at the cost of slightly higher conducted EMI.

FAQ
What is the maximum continuous input power supported by ICE3A2065ZXKLA1?
At 230VAC ±15% and Ta=75°C with no heatsink, ICE3A2065ZXKLA1 supports up to 57W continuous input power. This rating assumes standard DIP-7 PCB layout with 2oz copper and minimal thermal relief. Derating applies above 75°C ambient or with reduced copper area.
Does ICE3A2065ZXKLA1 require an external startup resistor?
No. ICE3A2065ZXKLA1 integrates a 650V startup cell that draws initial current directly from the rectified AC line through the CoolMOS™ drain, eliminating the need for an external high-voltage startup resistor and associated power loss.
How does Active Burst Mode differ from conventional burst mode in this IC?
In Active Burst Mode, the controller remains fully operational between switching bursts-maintaining feedback loop monitoring and enabling immediate response to load steps. Conventional burst modes disable the entire control circuit, causing output voltage droop and delayed recovery.
Can ICE3A2065ZXKLA1 be used in continuous conduction mode (CCM) flyback designs?
Yes. While optimized for discontinuous conduction mode (DCM) and quasi-resonant operation, ICE3A2065ZXKLA1 supports CCM via its 72% maximum duty cycle and precise current sensing. Transformer design must ensure demagnetization within each cycle to avoid saturation.
