Product details
Overview
ICE3BR2565JFXKSA2 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-TO220-6-247 FullPak package. It delivers 106W maximum input power 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 - deployed in DVD R/W, set-top boxes, and high-power AC/DC adapters.
For engineers reviewing the ICE3BR2565JFXKSA2 datasheet, ICE3BR2565JFXKSA2 pinout, ICE3BR2565JFXKSA2 application, or ICE3BR2565JFXKSA2 equivalent, key selection criteria include its integrated 650V CoolMOS®, active burst mode response (<1% output ripple), auto-restart protection behavior, BA-pin extendable blanking window, and BiCMOS-based 10.5–25V VCC operating range.
Technical Context
This controller implements a current-mode PWM architecture with leading-edge blanking, propagation delay compensation, and precise peak current limiting (±5% tolerance) to ensure stable power delivery across 85–265VAC inputs. Its BiCMOS process enables wide VCC operation and integrates soft start (20ms), oscillator jitter, and gate driver logic in a single die.
The device combines control and power stages: the Drain pin connects directly to the 650V CoolMOS® drain and HV startup cell, while CS senses source current for cycle-by-cycle limiting. The BA pin serves dual roles - extending blanking time via external capacitor and enabling external auto-restart by pulling below 0.33V - eliminating discrete protection components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650V - avalanche-rated drain-source voltage supports universal AC input without external snubber stress |
| fOSC | 67kHz fixed - internally generated switching frequency reduces timing component count and improves EMI predictability |
| RDS(on) | 2.56Ω @ Tj=25°C - low conduction loss enables 106W open-frame design at 50°C ambient with 2.7K/W heatsink |
| Standby Power | <100mW - achieved via Active Burst Mode with immediate load-jump response and <1% output voltage ripple |
| VCC Range | 10.5–25V - wide supply range accommodates varied auxiliary winding designs and improves light-load efficiency |
| Max Duty Cycle | 75% - limits transformer reset margin and ensures safe operation under peak line and overload conditions |
| Current Limit Tolerance | ±5% overall - enables accurate transformer sizing and consistent power limiting across temperature and line variations |
Pinout & Package
Package: PG-TO220-6-247 FullPak - thermally enhanced through-hole package with isolated drain tab, optimized for high-power SMPS layouts and heatsink mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1. Drain | Drain of integrated CoolMOS® and HV startup cell input | Direct connection to AC rectified input; carries full primary-side switching current and enables self-biasing startup |
| 2. CS | Current sense input | Senses voltage across external sense resistor in CoolMOS® source path; triggers cycle-by-cycle overcurrent shutdown |
| 3. BA | Extendable blanking & external auto-restart enable | Pulling below 0.33V forces auto-restart; adding capacitor extends blanking from 20ms to prevent false trip during transient overloads |
| 4. VCC | Controller supply input | Accepts 10.5–25V DC; powers internal circuitry after startup; UVLO threshold at 10.5V (off) / 18V (on) |
| 5. GND | Controller ground reference | Low-impedance return for control logic and feedback circuitry; separate from power ground in layout best practice |
| 6. FB | Feedback input | Receives optocoupler signal from secondary side; controls duty cycle in normal mode and sole regulation signal in Active Burst Mode |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3BR1765JFXKSA2 | 17Ω RDS(on), lower power rating (65W), same 67kHz fOSC and Active Burst Mode | Targeted for ≤65W DVD players and low-cost STBs; insufficient for 106W designs | Select when cost-sensitive, lower-power applications eliminate need for 2.56Ω conduction loss |
| ICE3BR4765JFXKSA2 | 4.7Ω RDS(on), 85W max input power, identical pinout and feature set | Mid-range power tier for 75W adapters; higher conduction loss than ICE3BR2565JF but lower cost | Choose where thermal margin allows 4.7Ω RDS(on) and 85W suffices for target BOM cost target |

FAQ
What is the maximum continuous output power achievable with ICE3BR2565JFXKSA2?
The ICE3BR2565JFXKSA2 supports up to 106W maximum input power in an open-frame design at Ta=50°C, Tj=125°C, and RthSA=2.7K/W heatsink. Actual output power depends on transformer design, cooling, and input voltage range (85–265VAC). At 230VAC ±15%, typical output is 12V/8.8A or 19V/5.6A with >87% efficiency.
How does the BA pin function in overload protection and blanking extension?
The BA pin provides two functions: (1) pulling it below 0.33V forces immediate entry into auto-restart mode, and (2) connecting a capacitor from BA to GND extends the internal 20ms blanking window to delay overload detection. This prevents false triggering during short-duration high-current events like motor startup or capacitor charging.
Does ICE3BR2565JFXKSA2 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 simplifies PCB layout. The startup cell disables automatically once VCC exceeds the 18V UVLO turn-on threshold.
What is the role of frequency jitter in EMI compliance?
Frequency jitter modulates the 67kHz switching frequency within a defined spread spectrum, dispersing harmonic energy across a wider bandwidth. This lowers peak conducted and radiated EMI amplitudes, easing compliance with EN55022 Class B and FCC Part 15 standards without requiring larger input filters or additional shielding.
