Product details
Overview
ICE3B2065PBKSA1 from Infineon Technologies is a fully integrated off-line SMPS current-mode controller with built-in 650V depletion CoolMOS™ and startup cell, designed for AC/DC flyback converters in universal-input (85–265 VAC) power supplies. It delivers up to 57W continuous input power at 230VAC ±15%, operates at fixed 67 kHz switching frequency, features ±5% peak current limiting tolerance, and achieves <100 mW standby power via Active Burst Mode.
For engineers reviewing the ICE3B2065PBKSA1 datasheet, ICE3B2065PBKSA1 pinout, ICE3B2065PBKSA1 application, or ICE3B2065PBKSA1 equivalent, key selection criteria include its integrated high-voltage switch, auto-restart protection suite (overtemperature, overvoltage, open-loop, undervoltage), adjustable blanking window for load-jump immunity, and PG-TO220-6-47 isolated-drain package enabling simplified heatsinking and creepage compliance.
Technical Context
The ICE3B2065PBKSA1 integrates a 650V avalanche-rugged depletion CoolMOS™ transistor with an internal current-mode PWM controller, eliminating external HV startup resistors and reducing BOM count. Its control architecture includes precise leading-edge blanking, propagation delay compensation, and user-defined soft-start timing.
It implements Active Burst Mode-where the controller remains active during light-load cycles-to deliver immediate response to load jumps and maintain output ripple below 1%. Protection logic triggers Auto Restart Mode on VCC undervoltage, overtemperature, output overvoltage, overload, or open-loop conditions, ensuring system robustness without external latch circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | Fixed 67 kHz - enables predictable EMI filtering and transformer design with stable timing margins. |
| Drain Voltage Rating | 650 V - supports direct connection to universal AC mains after bridge rectification without external snubber. |
| RDS(on) | 3.00 Ω @ Tj = 25°C - determines conduction loss and thermal rise in continuous operation at 50W output. |
| Peak Current Limit Tolerance | ±5% - ensures consistent transformer sizing and secondary diode selection across production lots. |
| Standby Power | <100 mW at no load - meets stringent Energy Star and EU CoC Tier 2 requirements without auxiliary winding. |

| Startup Cell | Integrated 650V depletion CoolMOS™ startup cell - eliminates external high-voltage resistor network and associated power loss. |
Pinout & Package
ICE3B2065PBKSA1 uses the PG-TO220-6-47 package: isolated drain tab (pin 1), electrically separated from internal controller ground; 6-pin through-hole outline with 2.7 K/W thermal resistance to ambient (with external heatsink); RoHS-compliant Pb-free plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 Drain | High-side power switch drain terminal | Directly connects to rectified AC line; requires ≥4 mm creepage clearance; serves as heatsink mounting surface. |
| 3 CS | Current sense input | Monitors primary-side current via sense resistor; includes internal leading-edge blanking (500 ns typical) to reject switching noise. |
| 4 GND | Controller ground reference | Low-noise analog/digital ground return; separate from power ground path to minimize noise coupling into FB/CS nodes. |
| 5 VCC | Controller supply input | Accepts 10.5–25 V; powers internal logic and gate driver; triggers auto-restart if voltage drops below 8.5 V. |
| 6 SoftS | Soft-start timing capacitor node | Connects external capacitor to set ramp-up time for duty cycle; prevents inrush current and overshoot at startup. |
| 7 FB | Feedback error amplifier input | Receives optocoupler signal from secondary side; controls burst mode entry/exit and regulates output voltage precision. |
Key Features
| Feature | Design Value |
|---|---|
| Active Burst Mode | Enables immediate load-step response with <1% output voltage ripple at light load-no blackouts during transient recovery. |
| Adjustable Blanking Window | User-configurable via external resistor to suppress false overcurrent trips during high di/dt load jumps. |
| Auto Restart Protection | Self-resetting fault recovery for overtemperature, VCC overvoltage, open-loop, overload, and VCC undervoltage-no manual reset required. |
| Integrated Startup Cell | 650V depletion CoolMOS™ eliminates 1–2 MΩ HV startup resistors, reducing board space and no-load losses by ~15 mW. |
| Precise Peak Current Limit | ±5% tolerance enables consistent transformer design across manufacturing batches and temperature range (−40°C to +125°C). |

FAQ
What is the purpose of the adjustable blanking window in ICE3B2065PBKSA1?
The adjustable blanking window suppresses false overcurrent detection during high di/dt events such as initial turn-on or sudden load steps. It is configured externally via a resistor connected to the SoftS pin and prevents unintended entry into Auto Restart Mode when primary current spikes occur due to transformer leakage inductance or snubber ringing.
How does Active Burst Mode differ from traditional burst mode in ICE3B2065PBKSA1?
Unlike conventional burst mode where the controller shuts down completely between bursts, ICE3B2065PBKSA1's Active Burst Mode keeps the internal oscillator and control logic continuously powered. This enables immediate response to load transients without output voltage dropout, maintaining ripple below 1% and eliminating audible transformer whine common in passive burst implementations.
Can ICE3B2065PBKSA1 operate without an auxiliary winding for VCC supply?
Yes-the integrated 650V startup cell allows direct connection to the rectified AC line for initial VCC charging. Once the main transformer generates sufficient auxiliary winding voltage, the internal startup cell is automatically disabled. This eliminates the need for external HV resistors and enables true single-winding operation in space-constrained designs.
What thermal derating applies to ICE3B2065PBKSA1 at elevated ambient temperatures?
At Ta = 75°C and Tj = 125°C with no external heatsink, the maximum continuous input power is rated at 28W (230VAC ±15%). With a 2.7 K/W external heatsink, the device sustains 50W at Ta = 50°C. Derating follows linear interpolation between these points, and PCB copper area directly impacts achievable power level.
