Product details
Overview
ICE3B5065I from Infineon Technologies is an off-line AC/DC current-mode PWM controller with integrated 650V depletion-mode CoolMOS™ power transistor, housed in PG-TO220-6-46 (I2Pak) package. It delivers up to 220W input power at 230VAC ±15%, operates at fixed 67kHz switching frequency, features <±5% peak current limiting tolerance, and supports Active Burst Mode for <100mW standby power in SMPS designs for industrial power supplies.
For engineers reviewing the ICE3B5065I datasheet, ICE3B5065I pinout, ICE3B5065I application, or ICE3B5065I equivalent, key selection criteria include its integrated high-voltage startup cell, adjustable blanking window for load-jump immunity, Auto Restart protection modes (overtemperature, overvoltage, open-loop), and isolated drain package enabling simplified heatsinking in universal-input flyback converters.
Technical Context
The ICE3B5065I integrates a 650V avalanche-rugged CoolMOS™ transistor with a dedicated current-mode PWM controller featuring internal leading-edge blanking and propagation delay compensation. Its control unit implements Active Burst Mode triggered by feedback voltage level, maintaining immediate load-step response without output blackout.
Protection logic includes five independent Auto Restart conditions-overtemperature, VCC overvoltage, output open-loop, overload, and VCC undervoltage-each forcing controlled shutdown and periodic restart attempts. The device uses a single external sense resistor for precise peak current detection with <±5% tolerance across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650V rated drain-source voltage - enables direct connection to 85–265VAC rectified input without external HV startup network |
| fSW | 67kHz fixed switching frequency - balances EMI performance and transformer size for mid-to-high power flyback topologies |
| RDS(on) | 0.95Ω typ @ 25°C - determines conduction loss and thermal design margin for 220W continuous input power rating |
| IOUT(max) | 220W max input power @ 230VAC ±15% - defines usable output power envelope in open-frame design with RthCA=2.7K/W |
| Current Limit Tolerance | <±5% overall - ensures consistent transformer sizing and secondary diode selection across production lots and temperature range |
| Standby Power | <100mW @ no load - achieved via Active Burst Mode with feedback-controlled gate drive enable/disable cycling |
| Max Duty Cycle | 72% - sets minimum achievable transformer turns ratio and limits peak primary current under low-line conditions |
Pinout & Package
ICE3B5065I uses the PG-TO220-6-46 (I2Pak) package with isolated drain tab for direct heatsink mounting and wide creepage distance. Pin 1 is the high-voltage drain terminal; pins 3–7 serve control functions with GND referenced to source potential.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Drain | 650V CoolMOS™ drain node - connects directly to rectified AC input; electrically isolated from package tab for safe heatsinking |
| 3 | CS | Current sense input - monitors source voltage drop across external shunt to implement cycle-by-cycle peak current limiting |
| 4 | GND | Controller ground reference - tied to CoolMOS™ source; forms return path for FB, SoftS, and internal logic |
| 5 | VCC | Internal supply rail - powered via auxiliary winding; regulated to 14.5V with UVLO threshold at 9.2V |
| 6 | SoftS | Soft-start timing node - external capacitor sets ramp time for controlled output voltage rise and inrush current limiting |
| 7 | FB | Feedback input - voltage-controlled entry into Active Burst Mode and regulation loop error amplification |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 650V CoolMOS™ + controller | Eliminates external HV startup circuitry and gate driver, reducing BOM count by ≥4 components in flyback designs |
| Active Burst Mode | Delivers <100mW standby power while maintaining real-time load-step response - no output voltage sag during light-to-heavy transitions |
| Adjustable blanking window | Prevents false overcurrent triggering during transient load jumps, enabling stable operation under dynamic line/load conditions |
| Auto Restart protection suite | Five independent fault responses (OTP, OVP, OLP, UVP, open-loop) - avoids latch-off failures and supports field-recoverable systems |
| Precise current limiting | <±5% tolerance ensures consistent power delivery and simplifies safety certification testing across operating temperature range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line SMPS controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3B5565I | Lower RDS(on) (0.79Ω vs. 0.95Ω), higher 240W input power rating | Suitable for same topology but requires larger heatsink footprint or lower ambient temperature for full derating | Select when >220W continuous output or tighter thermal margin is required; otherwise ICE3B5065I offers optimal cost/performance balance |
| ICE3B3565I | Higher RDS(on) (1.55Ω), 170W input power rating, identical 67kHz fSW and pinout | Matches lower-power designs (<170W) with reduced conduction loss budget and smaller heatsink | Drop-in replacement for cost-sensitive 100–150W applications where ICE3B5065I's headroom is unnecessary |
Compared with ICE3B5565I and ICE3B3565I, ICE3B5065I provides the optimal trade-off between conduction loss, thermal management, and bill-of-materials cost for 180–220W universal-input flyback converters - avoiding overdesign while ensuring robust operation under worst-case line and load transients.

FAQ
What is the maximum continuous input power rating for ICE3B5065I?
The ICE3B5065I supports up to 220W continuous input power at 230VAC ±15% in an open-frame design with external heatsink (RthCA = 2.7K/W), ambient temperature of 50°C, and junction temperature limited to 125°C. This rating assumes proper PCB copper area and thermal interface material per Infineon's layout guidelines.
Does ICE3B5065I require an external startup resistor?
No. ICE3B5065I integrates a 650V startup cell that draws initial current directly from the rectified AC line through the internal depletion-mode CoolMOS™, eliminating the need for an external high-voltage startup resistor or auxiliary winding during initial power-up.
How does Active Burst Mode reduce standby power below 100mW?
Active Burst Mode dynamically disables the PWM gate driver while keeping the control circuit active. The FB pin voltage determines burst frequency: at light loads, the controller cycles between short active bursts and extended sleep periods, minimizing switching and quiescent losses while retaining immediate load-step response capability.
What protection features trigger Auto Restart Mode?
Auto Restart Mode activates for five distinct fault conditions: overtemperature (Tj > 150°C), VCC overvoltage (>25V), output open-loop (FB > 2.5V), overload or short-circuit (CS > 1.2V), and VCC undervoltage (<9.2V). Each condition forces shutdown followed by periodic restart attempts until fault clearance.
