Product details
Overview
ICE3BR0665JFXKSA1 from Infineon Technologies is an integrated off-line SMPS current-mode controller with a 650V avalanche-rugged CoolMOS® power transistor and built-in startup cell in PG-TO220-6-347 FullPak package. It delivers 259W at 230VAC ±15%, operates at a fixed 67kHz switching frequency, features active burst mode for <100mW standby power, and includes internal frequency jitter for EMI reduction-used in DVD R/W, set-top boxes, and high-power AC/DC adapters.
For engineers reviewing the ICE3BR0665JFXKSA1 datasheet, ICE3BR0665JFXKSA1 pinout, ICE3BR0665JFXKSA1 application, or ICE3BR0665JFXKSA1 equivalent, key selection considerations include its integrated 650V CoolMOS®, ±5% peak current limiting tolerance, 20ms built-in blanking window with extendable timing via BA-pin capacitor, BiCMOS-based 10.5–25V VCC operating range, and auto-restart protection for overload, overtemperature, and overvoltage conditions.
Technical Context
The ICE3BR0665JFXKSA1 implements a current-mode PWM control architecture with leading-edge blanking, propagation delay compensation, and precise peak-current sensing via the CS pin to enable stable wide-input-range operation (85–265VAC). Its BiCMOS process supports a 10.5–25V VCC supply and enables fast load-jump response during active burst mode with <1% output voltage ripple.
It integrates a high-voltage startup cell directly connected to the Drain terminal, eliminating external startup resistors and reducing light-load power loss. Protection logic combines fixed 20ms blanking with externally extendable duration (via BA pin capacitor), auto-restart on open-loop, overvoltage, overtemperature, and undervoltage faults, and soft driving with frequency jitter to suppress conducted EMI without enlarging input filters.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
ICE3BR0665JFXKSA1 is housed in a PG-TO220-6-347 FullPak package-a thermally enhanced variant of TO-220 with isolated drain tab and 6-pin vertical lead frame optimized for high-power SMPS integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: Drain | Drain of integrated CoolMOS® and HV node of startup cell | Directly connects to rectified AC line; carries full primary-side switching current and enables resistorless startup |
| 2: CS | Current sense input | Samples source current via external shunt; triggers immediate gate turn-off at precise peak current threshold |
| 3: BA | Extended blanking & external auto-restart enable | Pull <0.33V to force auto-restart; add capacitor to ground to extend 20ms blanking time for high-current transients |
| 4: VCC | Controller supply input | Accepts 10.5–25V; powers internal BiCMOS circuitry and gate driver; UVLO threshold at 10.5V |
| 5: GND | Controller ground reference | Low-impedance return path for CS, FB, and internal logic; electrically isolated from Drain tab |
| 6: FB | Feedback input | Receives optocoupler signal from secondary side; controls duty cycle in PWM mode and regulates burst frequency in standby |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 650V CoolMOS® + startup cell | Eliminates external HV startup resistor, reduces component count, and improves light-load efficiency |
| Active Burst Mode | Maintains closed-loop regulation at no load using same optocoupler path, enabling immediate load response and <1% VOUT ripple |
| Built-in frequency jitter | Spreads switching energy across narrowband spectrum, lowering peak EMI by up to 10dB and shrinking input filter size |
| Extendable blanking window | 20ms base + capacitor-tunable extension prevents nuisance tripping during high di/dt events like motor startup |
| BiCMOS technology | Enables 10.5–25V VCC range and robust gate drive under low-VCC brownout conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line SMPS controller with integrated MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3BR1765JFXKSA1 | Same FullPak package but 650V CoolMOS® with higher RDS(on) (0.72Ω) and lower max power (210W @ 230VAC) | Targeted at mid-power adapters (≤210W); less suitable for 250W+ designs due to higher conduction loss | Select when thermal budget allows higher RDS(on) and cost sensitivity outweighs peak power need |
| ICE3B0565JFXKSA1 | Same architecture but 500V CoolMOS® (RDS(on) = 0.59Ω); not rated for 265VAC universal input | Limited to 230VAC-only or regulated DC input; unsafe for 265VAC surge conditions | Choose only for fixed 230VAC mains regions with strict cost targets and no surge requirement |
Compared with ICE3BR1765JFXKSA1 and ICE3B0565JFXKSA1, the ICE3BR0665JFXKSA1 uniquely balances 650V ruggedness, 0.59Ω conduction loss, and 259W capability-making it the sole option among the three qualified for universal-input 250W+ adapters requiring both safety margin and efficiency.

FAQ
What is the maximum continuous output power achievable with ICE3BR0665JFXKSA1?
The ICE3BR0665JFXKSA1 supports up to 259W in open-frame designs at Ta=50°C, Tj=125°C, and with an external heatsink thermal resistance of 2.7K/W. This rating assumes 230VAC ±15% input and accounts for conduction loss (0.59Ω RDS(on)), switching loss, and thermal derating-verified per Infineon's input power curve in the official datasheet.
Does ICE3BR0665JFXKSA1 require an external startup resistor?
No. The device integrates a high-voltage startup cell connected directly to the Drain pin, eliminating the need for an external startup resistor. This reduces component count, improves light-load efficiency, and removes associated power loss-confirmed in the functional description and block diagram of the official datasheet.
How does the BA pin function in overload protection?
The BA pin serves dual roles: (1) adding a capacitor to ground extends the default 20ms blanking window to prevent false overload detection during high di/dt transients; (2) pulling BA below 0.33V forces immediate entry into auto-restart mode. Both functions are electrically verified in the pin functionality section of the datasheet.
Can ICE3BR0665JFXKSA1 operate across the full 85–265VAC input range?
Yes. It is explicitly rated for 85–265VAC universal input operation, supported by its 650V drain rating, BiCMOS-based 10.5–25V VCC range, and internal propagation delay compensation that maintains stable power limiting across line voltage variation-documented in the "Operating Range" and "Input Power Curve" sections of the datasheet.
