Product details
Overview
ICE3BR1765JXKLA1 from Infineon Technologies is an off-line SMPS current-mode controller IC integrating a 650V CoolMOS® power transistor, startup cell, and frequency jitter functionality in a PG-DIP-8 package. It delivers 46W max input power at 230VAC ±15%, operates at a fixed 65kHz switching frequency, supports active burst mode for <50mW standby power, and targets low-cost AC/DC adapters for DVD players, set-top boxes, and similar consumer electronics.
For engineers reviewing the ICE3BR1765JXKLA1 datasheet, ICE3BR1765JXKLA1 pinout, ICE3BR1765JXKLA1 application, or ICE3BR1765JXKLA1 equivalent, key selection criteria include integrated high-voltage MOSFET capability, built-in soft start and blanking window, auto-restart protection modes, and EMI reduction via frequency jitter and soft gate driving.
Technical Context
This IC implements a current-mode PWM control architecture with internal oscillator, propagation delay compensation, and leading-edge blanking (220ns) to ensure stable regulation under dynamic load jumps. The control unit integrates active burst mode logic that maintains optocoupler-based feedback control even at no-load, enabling precise VOUT regulation while minimizing standby losses.
The integrated 650V CoolMOS® features avalanche ruggedness and is directly driven by an internal gate driver with soft-switching characteristics. Startup is handled autonomously via a high-voltage startup cell connected to the Drain pin, eliminating the need for external startup resistors and reducing light-load power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650V - Enables direct connection to universal AC input (85–265VAC) without external HV starter or pre-regulator. |
| fSW | 65kHz fixed - Simplifies EMI filter design and ensures predictable transformer sizing for compact 30–50W SMPS designs. |
| RDS(on) | 1.70Ω @ Tj=25°C - Delivers 46W max input power at 230VAC with minimal conduction loss in integrated MOSFET. |
| Standby Power | <50mW - Achieved via active burst mode with full optocoupler feedback retention, meeting stringent energy efficiency standards. |
| Max Duty Cycle | 75% - Supports wide input voltage range and transient overload handling without saturation in current-sense path. |
| Current Limit Tolerance | ±5% overall - Ensures consistent overcurrent protection across temperature and process variation, critical for production reliability. |
| VCC Range | 10.5–25V - Accommodates wide auxiliary supply variation and enables flexible biasing schemes in multi-output topologies. |
Pinout & Package
ICE3BR1765JXKLA1 is housed in a PG-DIP-8 package with creepage/clearance optimized for reinforced insulation in AC/DC converters. Pins 4 and 5 are internally shorted as dual Drain connections to the integrated CoolMOS®.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (BA) | Extended Blanking & Auto-Restart Enable | Capacitor-adjustable blanking time (base 20ms); pull <0.33V to force immediate auto-restart shutdown. |
| 2 (FB) | Feedback Input | Primary regulation interface for optocoupler output; sole control signal during active burst mode. |
| 3 (CS) | Current Sense | Senses source voltage of integrated CoolMOS®; triggers immediate gate turn-off at internal current limit threshold. |
| 4 & 5 (Drain) | CoolMOS® Drain | Dual pins shorted internally to handle high dv/dt and reduce parasitic inductance in high-frequency switching. |
| 6 (n.c.) | No Connect | Internally unconnected; must remain floating per datasheet - no PCB trace or component attachment. |
| 7 (VCC) | Controller Supply | BiCMOS-compatible 10.5–25V rail; powers all internal circuitry including gate driver and protection units. |
| 8 (GND) | Controller Ground | Analog/digital reference return; requires low-impedance layout separation from power ground to avoid noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in frequency jitter | Reduces peak EMI amplitude by spreading switching energy across ~±3kHz band, easing compliance with CISPR-22 Class B limits. |
| Active burst mode with opto feedback | Maintains closed-loop regulation at no-load via FB pin, eliminating output voltage drift and enabling fast wake-up on load step. |
| Extendable blanking window | Base 20ms blanking extended via external capacitor on BA pin - prevents false OCP triggering during high-current transients (e.g., motor startup). |
| Integrated startup cell | Connects directly to Drain pin; eliminates external high-voltage resistor, cutting no-load power loss by ~15mW typical. |
| Propagation delay compensation | Automatically adjusts current-sense timing to cancel gate driver and MOSFET switching delays, improving current limit accuracy across temperature. |
Applications
| DVD/Blu-ray Player Power Supply | Set-Top Box AC/DC Adapter |

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 |
|---|---|---|---|
| ICE3BR1765JZ | Same die, PG-DIP-8 package with different marking code (no XKL suffix); identical electrical specs and pinout. | No functional difference - used interchangeably in same PCB layouts and BOMs. | Select when standard Infineon part numbering is required; identical sourcing and qualification status. |
| ICE3AR1765J | Removes frequency jitter feature; otherwise identical architecture, pinout, and 65kHz operation. | Lacks EMI spread-spectrum capability - may require larger input filter in noise-sensitive environments. | Choose only if jitter is unnecessary and lower EMI test cost outweighs performance trade-off. |
Compared with ICE3BR1765JZ, the XKL suffix denotes tape-and-reel packaging for automated assembly; versus ICE3AR1765J, the 'B' variant adds jitter for robust EMI compliance without layout changes or added components.

FAQ
What is the purpose of the BA pin on ICE3BR1765JXKLA1?
The BA pin serves two distinct functions: (1) extending the internal 20ms blanking window via an external capacitor to prevent false overcurrent trips during high-load transients, and (2) enabling external forced auto-restart by pulling the pin below 0.33V. Both functions share the same terminal but operate independently based on voltage threshold and timing conditions.
Does ICE3BR1765JXKLA1 require an external startup resistor?
No. ICE3BR1765JXKLA1 integrates a high-voltage startup cell connected directly to the Drain pin, eliminating the need for an external high-voltage resistor. This reduces no-load power consumption by ~15mW and simplifies PCB layout, especially in space-constrained adapters.
How does active burst mode maintain output regulation at no-load?
Unlike conventional burst modes that disable feedback, ICE3BR1765JXKLA1's active burst mode keeps the FB pin fully active and responsive to the optocoupler signal. The controller continues sampling FB voltage between bursts and adjusts burst frequency dynamically to hold output voltage within ±3%, ensuring tight regulation without secondary-side shunt regulators.
Can ICE3BR1765JXKLA1 be used in continuous conduction mode (CCM) flyback designs?
Yes. With its 75% maximum duty cycle, propagation delay compensation, and precise ±5% current limit tolerance, ICE3BR1765JXKLA1 supports both discontinuous (DCM) and continuous conduction mode flyback topologies up to 46W input power, provided transformer design accounts for peak current handling and core reset.
