Product details
Overview
ICE3BR1065JXKLA1 from Infineon Technologies is an integrated off-line SMPS current-mode controller with a monolithically embedded 650V CoolMOS® power transistor and startup cell in PG-DIP-8 package, operating at a fixed 65 kHz switching frequency with ±5% current-limit tolerance, frequency jitter for EMI reduction, and active burst mode enabling <50 mW standby power - deployed in DVD players, set-top boxes, and low-cost AC/DC adapters.
For engineers reviewing the ICE3BR1065JXKLA1 datasheet, ICE3BR1065JXKLA1 pinout, ICE3BR1065JXKLA1 application, or ICE3BR1065JXKLA1 equivalent, key selection considerations include integrated high-voltage MOSFET capability, DIP-8 thermal and layout compatibility, active burst mode behavior under light load, and BA-pin configurable blanking/auto-restart functionality.
Technical Context
This IC implements a BiCMOS-based current-mode PWM controller with internal oscillator, propagation-delay-compensated current sensing, and leading-edge blanking. It integrates a 650V avalanche-rugged CoolMOS® transistor with drain-connected startup cell, eliminating external high-voltage startup resistors.
The control architecture supports dual blanking modes (20 ms fixed + capacitor-extendable), external auto-restart enable via BA pin (<0.33 V trigger), and soft gate driving with frequency jitter to suppress EMI peaks. VCC operates from 10.5 V to 25 V, and maximum duty cycle is limited to 75%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 65 kHz fixed - enables predictable EMI filtering and transformer design without external timing components. |
| CoolMOS® Breakdown Voltage | 650 V - supports universal AC input (85–265 VAC) with margin for line surges and snubber transients. |
| Current Limit Tolerance | ±5% - ensures precise overcurrent protection across temperature and process variation without calibration. |
| Standby Power | <50 mW in Active Burst Mode - meets stringent EU CoC Tier 2 and Energy Star requirements for no-load operation. |
| VCC Operating Range | 10.5 V to 25 V - accommodates wide auxiliary winding regulation and simplifies bias supply design. |
| Max Duty Cycle | 75% - limits peak primary current and improves transformer utilization in flyback topologies. |
| Integrated Startup Cell | Drain-connected, HV-enabled - removes need for external 1 MΩ+ startup resistor, reducing BOM count and no-load losses. |
Pinout & Package
Package: PG-DIP-8 (Plastic Dual-In-Line Package, 8-pin, 0.3 inch width, creepage ≥5.0 mm). Pins 4 and 5 are internally shorted as common Drain connection for the integrated CoolMOS®.
| 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 | Primary-side regulation interface - accepts optocoupler signal to modulate duty cycle and enter burst mode at light load. |
| 3 (CS) | Current Sense | Senses source voltage of integrated CoolMOS® - triggers immediate gate turn-off when threshold reached (precise peak-current limiting). |
| 4 & 5 (Drain) | CoolMOS® Drain Terminal | High-side power switch node - connects directly to primary winding and snubber network; pins shorted internally. |
| 6 (n.c.) | No Connection | Unbonded pad - must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
| 7 (VCC) | Controller Supply | Power rail for internal logic and gate driver - regulated by auxiliary winding; UVLO activates at 10.5 V, latches off above 25 V. |
| 8 (GND) | Controller Ground | Reference return for CS, FB, BA, and internal bias - requires low-inductance connection to power ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in Frequency Jitter | Spreads 65 kHz fundamental across ±4% bandwidth - reduces peak radiated emissions without external spread-spectrum circuitry. |
| Active Burst Mode | Dynamically disables switching cycles while preserving feedback loop integrity - achieves <50 mW standby with stable output regulation. |
| Extendable Blanking Window | 20 ms base + capacitor-tunable extension - prevents false overcurrent trips during high di/dt load transients (e.g., disc motor spin-up). |
| Soft Gate Driving | Controlled slew rate on integrated driver output - minimizes dv/dt-induced EMI and reduces CoolMOS® gate oscillation risk. |
| Integrated Startup Cell | Drain-referenced HV current source - eliminates external startup resistor, cutting no-load loss by ~15 mW and improving reliability. |
Applications
| Consumer DVD/Blu-ray Player Power Supply | Set-Top Box AC/DC Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated SMPS controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3B0565J | Same CoolSET®-F3R family but 500 V CoolMOS® - lower breakdown margin for 265 VAC surge handling. | Limited to 115 VAC-only or derated universal-input designs; unsuitable for robust 265 VAC operation. | Select only if input is strictly 90–132 VAC and cost sensitivity outweighs surge immunity needs. |
| ICE5QSBG | QR flyback controller with 650 V superjunction MOSFET, 65 kHz, but no integrated startup cell or BA-pin extendable blanking. | Requires external startup resistor and separate blanking capacitor; lacks active burst mode - standby >100 mW. | Prefer when quasi-resonant operation is required for higher efficiency at medium load, accepting higher BOM count and standby penalty. |
Compared with ICE3B0565J and ICE5QSBG, ICE3BR1065JXKLA1 uniquely combines 650 V ruggedness, integrated startup, capacitor-extendable blanking, and sub-50 mW burst mode - making it optimal for cost-sensitive, space-constrained universal-input adapters where reliability and ultra-low standby are mandatory.

FAQ
What is the function of the BA pin on ICE3BR1065JXKLA1?
The BA pin serves two distinct functions: (1) extending the internal 20 ms blanking window via an external capacitor to ground for high-di/dt overload immunity, and (2) enabling external forced auto-restart by pulling the pin below 0.33 V. Both functions share the same terminal but operate independently based on voltage threshold and timing conditions.
Does ICE3BR1065JXKLA1 require an external startup resistor?
No - it integrates a drain-connected high-voltage startup cell that draws current directly from the CoolMOS® drain during initial power-up, eliminating the need for an external high-value resistor. This reduces no-load losses by ~15 mW and improves system reliability by removing a common failure point.
How does Active Burst Mode achieve <50 mW standby power?
Active Burst Mode dynamically disables entire switching cycles while maintaining feedback loop supervision via the FB pin. The controller monitors output regulation through the optocoupler and only resumes bursts when output voltage drops below threshold - minimizing average switching loss without sacrificing regulation accuracy or response time.
Can ICE3BR1065JXKLA1 be used in QR (quasi-resonant) flyback topologies?
No - it is a fixed-frequency current-mode controller optimized for continuous conduction mode (CCM) and discontinuous conduction mode (DCM) flyback operation. It lacks zero-current detection circuitry, valley-switching logic, or variable frequency control required for QR operation.
