Product details
Overview
ICE3B0565JXKLA1 from Infineon Technologies is an integrated off-line SMPS current-mode controller with built-in 650V CoolMOS® power transistor and startup cell in PG-DIP-8 package, operating at fixed 67 kHz switching frequency, delivering up to 25 W output power at 230 VAC ±15%, and featuring frequency jittering for EMI reduction and active burst mode enabling <100 mW standby power.
For engineers reviewing the ICE3B0565JXKLA1 datasheet, ICE3B0565JXKLA1 pinout, ICE3B0565JXKLA1 application, or ICE3B0565JXKLA1 equivalent, key selection considerations include integrated high-voltage switch rating (650 V), precise peak current limiting (<±5% tolerance), adjustable blanking window for load-jump reliability, auto-restart protection modes, and DIP-8 footprint compatibility with board-level thermal management requirements.
Technical Context
The ICE3B0565JXKLA1 implements a BiCMOS-based current-mode PWM architecture with internal oscillator, leading-edge blanking, and propagation delay compensation to maintain stable power delivery across universal AC input (85–265 VAC). Its integrated CoolMOS® drain connects directly to the high-side switching node, while the CS pin senses source current for cycle-by-cycle peak current limiting.
Control logic includes dedicated SoftS pin functionality for soft-start ramp generation, frequency jitter modulation, blanking window adjustment, and auto-restart fault detection-all implemented via a single external capacitor. The FB pin accepts optocoupler feedback for CV/CC regulation and triggers active burst mode below ~0.4 V, maintaining tight output voltage ripple (<1%) even at no-load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | Fixed 67 kHz - enables predictable EMI filter design and transformer sizing without external timing components. |
| Integrated MOSFET Voltage Rating | 650 V avalanche-rugged CoolMOS® - supports direct connection to universal AC rectified bus without external HV starter or snubber. |
| Max Output Power | 25 W at 230 VAC ±15% - defines usable power envelope for compact adapters and low-cost SMPS designs. |
| Standby Power | <100 mW at 270 VAC no-load - meets stringent global energy efficiency standards (e.g., DOE Level VI, EU CoC Tier 2). |
| Current Limit Tolerance | <±5% overall - reduces transformer and secondary diode overdesign, lowering BOM cost and size. |
| VCC Operating Range | 10.3 V to 26 V - accommodates wide auxiliary supply variation in CV/CC secondary-side regulated topologies. |
| Duty Cycle Limit | 75% maximum - ensures safe operation margin under transient overload and line-dip conditions. |
Pinout & Package
ICE3B0565JXKLA1 is housed in PG-DIP-8 package with creepage/clearance optimized for reinforced insulation in AC/DC converters. Pins 4 and 5 are internally shorted to handle high-current drain return path; Pin 6 is NC and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SoftS) | Soft-start / Auto-restart / Jitter control | External capacitor sets soft-start time, blanking window duration, and jitter period-no separate RC networks required. |
| 2 (FB) | Feedback input | Accepts optocoupler signal to regulate output voltage/current; also triggers active burst mode when FB < 0.4 V. |
| 3 (CS) | Current sense input | Senses voltage across external sense resistor in CoolMOS® source path; enables accurate peak-current limiting and slope compensation. |
| 4 & 5 (Drain) | Integrated CoolMOS® drain terminal | High-side switching node connection; rated for 650 V DC and avalanche energy handling per JEDEC JESD24-11. |
| 6 (N.C.) | No connection | Internally isolated; must be left floating-no PCB trace or solder mask opening required. |
| 7 (VCC) | Controller supply input | Powered by auxiliary winding; UVLO thresholds (18 V on / 10.3 V off) ensure clean start-up and graceful shutdown. |
| 8 (GND) | Signal and power ground reference | Common return for CS sensing, FB divider, and gate driver; requires low-inductance layout to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Active Burst Mode | Maintains full feedback loop control during light/no-load operation, enabling immediate response to load jumps without output dropout. |
| Adjustable Blanking Window | Configured via SoftS capacitor to suppress false overcurrent trips during fast load transients-improves system robustness without extra components. |
| Frequency Jittering | Spreads spectral energy across ~±4% of 67 kHz center frequency, reducing peak EMI amplitude by >10 dB in conducted emissions tests. |
| Integrated Startup Cell | Draws 1.05 mA from Drain to charge VCC capacitor-eliminates external high-voltage startup resistor and associated power loss. |
| Precision Peak Current Limit | Internal comparator with <±5% tolerance over temperature-enables smaller transformer core and lower-cost secondary rectifier selection. |

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 |
|---|---|---|---|
| ICE3B0565J | Same die, identical electrical specs; differs only in marking and packaging (no 'XKLA1' suffix; standard reel vs. tape-and-reel variant). | No functional difference-used interchangeably in production where traceability or packaging format is not controlled. | Select ICE3B0565JXKLA1 when lot traceability, RoHS-compliant lead finish, or specific tape-and-reel configuration is required per OEM procurement policy. |
| ICE3B1565J | Higher RDS(on) (1.7 Ω vs. 4.7 Ω), lower max output power (42 W vs. 25 W), same 67 kHz frequency and feature set. | Better suited for higher-power adapters (>30 W) where thermal headroom allows larger heatsinking or lower switching losses. | Choose ICE3B1565J only if design requires >25 W output at 230 VAC and can accommodate higher conduction loss in CoolMOS® section. |
Compared with ICE3B0565J (identical function, different packaging) and ICE3B1565J (higher-power variant), ICE3B0565JXKLA1 offers optimal balance of standby efficiency, thermal performance, and component count reduction for sub-30 W universal-input SMPS-making it preferred for space-constrained consumer and industrial auxiliary supplies.

FAQ
What is the purpose of the SoftS pin in ICE3B0565JXKLA1?
The SoftS pin serves three integrated functions: soft-start ramp generation during power-up, adjustable blanking window control for high-load-jump immunity, and frequency jitter modulation during normal operation. An external capacitor to ground sets all three parameters-eliminating separate RC networks for startup, protection, and EMI reduction.
Does ICE3B0565JXKLA1 require an external startup resistor?
No. ICE3B0565JXKLA1 integrates a high-voltage startup cell connected directly to the Drain pin, delivering 1.05 mA to charge the VCC capacitor. This eliminates the need for an external high-voltage resistor, reducing power loss and component count while improving light-load efficiency.
How does active burst mode reduce standby power below 100 mW?
Active burst mode maintains continuous monitoring of the FB pin while drastically reducing switching activity-only activating the gate driver in short bursts when output regulation demands it. Combined with BiCMOS low-quiescent-current design and internal bias optimization, this achieves <100 mW no-load consumption at 270 VAC without compromising load-step response.
Can ICE3B0565JXKLA1 be used in continuous conduction mode (CCM) flyback designs?
Yes. ICE3B0565JXKLA1 supports both discontinuous conduction mode (DCM) and CCM flyback operation. Its current-mode control, precise peak current limiting, and propagation delay compensation ensure stable regulation and consistent power limiting across both modes-validated in Infineon's reference design AN2012-09 for 24 W CCM adapter.
