Product details
Overview
ICE3BR0665J from Infineon Technologies is an integrated off-line SMPS current-mode controller combining a 650V avalanche-rugged CoolMOS® power transistor, startup cell, and frequency-jitter PWM control in a single PG-DIP-8 package. It delivers 74W at 230VAC with fixed 65kHz switching, ±5% current-limit tolerance, and active burst mode enabling <50mW standby power - deployed in DVD players, set-top boxes, and low-cost AC/DC adapters.
For engineers reviewing the ICE3BR0665J datasheet, ICE3BR0665J pinout, ICE3BR0665J application, or ICE3BR0665J equivalent, key selection considerations include its integrated high-voltage MOSFET, jitter-enabled EMI reduction, extended blanking window via BA-pin capacitor, and auto-restart protection for overload, overtemperature, and open-loop faults.
Technical Context
The ICE3BR0665J implements a BiCMOS-based current-mode PWM architecture with internal oscillator (65kHz), leading-edge blanking (220ns), propagation delay compensation, and precise peak-current limiting (±5% tolerance). Its control unit integrates active burst mode with optocoupler feedback retention and soft-start timing (20ms).
It features a dedicated startup cell connected directly to the Drain pin, eliminating external startup resistors, and supports dual blanking modes: fixed 20ms base window and extendable duration via external capacitor on BA pin. Frequency jitter reduces EMI peaks without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | Fixed 65 kHz - enables predictable EMI filtering and transformer design without external timing components. |
| Integrated MOSFET VDS | 650 V - supports universal AC input (85–265 VAC) with avalanche ruggedness for surge immunity. |
| RDS(on) | 0.65 Ω @ Tj = 25°C - balances conduction loss and thermal performance for ≤74W continuous output. |
| Standby Power | <50 mW in Active Burst Mode - meets stringent no-load efficiency requirements for consumer electronics. |
| Current Limit Tolerance | ±5% overall - ensures consistent overcurrent protection across temperature and process variation. |
| VCC Operating Range | 10.5 V to 25 V - accommodates wide auxiliary supply variation and simplifies bias winding design. |
| Max Duty Cycle | 75% - provides sufficient on-time headroom for transient response while maintaining stability margin. |
Pinout & Package
ICE3BR0665J is housed in a PG-DIP-8 (Dual In-line Package) with creepage/clearance optimized for reinforced insulation in AC/DC converters. Pins 4 and 5 are internally shorted to handle high-current drain connection; Pin 6 is unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (BA) | Extended Blanking & Auto-Restart Enable | Capacitor-to-ground extends blanking time beyond 20 ms; pull <0.33 V forces immediate auto-restart shutdown. |
| 2 (FB) | Feedback Input | Accepts optocoupler signal to regulate output voltage; sole control path during Active Burst Mode. |
| 3 (CS) | Current Sense | Senses source voltage of integrated CoolMOS®; triggers immediate gate turn-off at internal current threshold. |
| 4 & 5 (Drain) | High-Voltage Drain Node | Internally shorted pins connect to CoolMOS® drain - carries full AC line-referred switching current. |
| 6 (n.c.) | No Connection | Unbonded pad - must remain floating; no PCB trace or component connection permitted. |
| 7 (VCC) | Controller Supply | Power input for internal circuitry; regulated by internal startup cell until UVLO threshold (18 V) is reached. |
| 8 (GND) | Signal Ground Reference | Common return for CS, FB, BA, and internal bias - requires low-inductance layout to avoid sensing errors. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in frequency jitter | Reduces peak EMI amplitude by spreading switching energy across a narrow band - eliminates need for external spread-spectrum circuitry. |
| Active Burst Mode with opto-retention | Maintains closed-loop regulation via FB pin during burst cycles - ensures tight output voltage control even at near-zero load. |
| Extendable blanking window | Base 20 ms blanking extended by external capacitor on BA pin - prevents false overcurrent trips during high di/dt load steps. |
| Integrated startup cell | Connected directly to Drain - removes external high-voltage startup resistor, cutting BOM count and improving light-load efficiency. |
| Soft gate driving | Controls dv/dt during CoolMOS® turn-on - reduces EMI generation and stress on snubber components without external gate resistors. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line SMPS controller with integrated HV MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3B0565J | Same PG-DIP-8 package and CoolSET®-F3R architecture but rated for 500 V VDS and 0.95 Ω RDS(on). | Limited to 230 VAC-only designs; lower power capability (≤49 W at 230 VAC) and higher conduction loss. | Select when input voltage is clamped to ≤264 VAC and cost sensitivity outweighs efficiency needs. |
| ICE2QS03G | Quasi-resonant controller without integrated MOSFET; requires external 650 V FET and separate startup circuitry. | Higher BOM count and layout complexity; lacks built-in jitter and active burst mode. | Choose when variable-frequency operation is preferred for ultra-low EMI or when discrete FET selection is mandatory for thermal management. |
Compared with ICE3B0565J and ICE2QS03G, the ICE3BR0665J uniquely combines 650 V integration, jitter-enabled EMI reduction, and sub-50 mW standby in one DIP-8 device - offering lowest component count and highest light-load efficiency for universal-input consumer SMPS.

FAQ
What is the purpose of the BA pin on the ICE3BR0665J?
The BA pin serves two distinct functions: extending the internal 20 ms blanking window via an external capacitor to ground (for high di/dt load jumps), and enabling external auto-restart by pulling the pin below 0.33 V to force immediate gate shutdown. Both functions operate independently and are validated in the datasheet's functional description and electrical characteristics tables.
Does the ICE3BR0665J require an external startup resistor?
No. The ICE3BR0665J integrates a high-voltage startup cell connected directly to the Drain pin, eliminating the need for an external high-voltage startup resistor. This reduces component count, improves light-load efficiency, and is confirmed in the block diagram, functional description, and application schematic sections of the official Infineon datasheet.
How does Active Burst Mode maintain output regulation on the ICE3BR0665J?
During Active Burst Mode, the FB pin remains fully active and retains closed-loop control via the optocoupler - unlike traditional burst modes that disable feedback. This allows continuous monitoring and adjustment of duty cycle per burst cycle, ensuring ±2% output voltage regulation even at 10 mA load, as verified in typical application waveforms and test data on page 16 of the datasheet.
Can the ICE3BR0665J be used in 230 VAC-only applications?
Yes - the ICE3BR0665J supports universal input (85–265 VAC) and is rated for 650 V drain-source breakdown. At 230 VAC ±15%, it delivers up to 74 W continuous output. Its 650 V rating provides sufficient margin for line surges and transients common in 230 VAC grids, as specified in the absolute maximum ratings table (Section 4.1) of the datasheet.
