Product details
Overview
ICE3A2065I from Infineon Technologies is an off-line AC/DC current-mode PWM controller with integrated 650V depletion-mode CoolMOS™ power transistor and startup cell, housed in PG-TO220-6-46 (I2Pak) package. It delivers up to 102W continuous input power at 230VAC ±15%, operates at fixed 100kHz switching frequency, features <±5% peak current limit tolerance, and supports Active Burst Mode for <100mW standby power in SMPS flyback converters.
For engineers reviewing the ICE3A2065I datasheet, ICE3A2065I pinout, ICE3A2065I application, or ICE3A2065I equivalent, this device is selected for high-efficiency, low-standby-power offline adapters requiring integrated high-voltage switching, precise current sensing, and robust auto-restart protection across wide input voltage ranges (85–265 VAC).
Technical Context
The ICE3A2065I integrates a 650V avalanche-rugged CoolMOS™ transistor with a current-mode PWM controller featuring internal oscillator (100kHz), leading-edge blanking, propagation delay compensation, and adjustable blanking window. Its control unit implements Active Burst Mode triggered by feedback signal level and Auto Restart Mode for overtemperature, overvoltage, overload, open-loop, and VCC undervoltage faults.
Startup is enabled via an internal 650V startup cell that draws current directly from the rectified AC line, eliminating external high-voltage resistors. The drain pin is electrically isolated from the package tab, enabling direct heatsink mounting without insulation, and the 2.7K/W thermal resistance (with external heatsink) supports 50W continuous output power at Ta=50°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650V - Enables direct connection to universal AC input (85–265 VAC) without pre-regulator or external HV startup network. |
| fSW | 100 kHz - Fixed frequency enables predictable EMI filter design and transformer sizing for compact 50–100W flyback topologies. |
| RDS(on) | 3.00 Ω @ 25°C - Optimized conduction loss for 102W max input power rating at 230VAC, balancing efficiency and thermal margin. |
| Ilim tolerance | <±5% - Tight current limit accuracy reduces transformer and secondary diode derating, lowering BOM cost and size. |
| Standby power | <100 mW - Achieved via Active Burst Mode with immediate load-jump response, meeting stringent global energy standards (e.g., DOE VI, CoC Tier 2). |
| Max duty cycle | 72% - Supports sufficient on-time for high step-down ratios in universal-input flyback designs with low Vout. |
| Thermal RthCA | 2.7 K/W - With external heatsink, enables 50W continuous output at Ta=50°C and Tj=125°C, simplifying thermal design. |
Pinout & Package
ICE3A2065I uses the PG-TO220-6-46 (I2Pak) package with isolated drain tab, enabling direct metal heatsink mounting without insulating pads. Pin 1 (Drain) is connected to the CoolMOS™ drain and the exposed metal tab; pins 3–7 are signal/control terminals on the plastic body side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Drain) | CoolMOS™ high-side switch drain terminal | Connected to primary winding of flyback transformer; electrically isolated from package tab for safe heatsink mounting. |
| 3 (CS) | Current sense input / CoolMOS™ source | Monitors primary current via sense resistor; also serves as CoolMOS™ source node-requires Kelvin connection for accurate sensing. |
| 4 (GND) | Controller ground reference | Low-noise analog/digital ground return for internal circuitry; separate from power ground path to minimize noise coupling. |
| 5 (VCC) | Internal controller supply input | Powered by auxiliary winding after startup; regulated internally to 14.6V typical; UVLO threshold at 9.2V. |
| 6 (SoftS) | Soft-start timing capacitor connection | Controls ramp-up time of internal reference to prevent inrush current; external capacitor sets soft-start duration. |
| 7 (FB) | Optocoupler feedback input | Regulates output voltage via optocoupler-connected error amplifier; 1.5V threshold triggers burst mode entry at light load. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 650V CoolMOS™ + controller | Reduces component count by eliminating external HV MOSFET, gate driver, and startup resistor-enabling <15 mm² PCB footprint reduction. |
| Active Burst Mode | Delivers <100mW no-load standby while maintaining immediate load-step response (<100 µs wake-up), avoiding output voltage blackout during transient loading. |
| Adjustable blanking window | Prevents false overcurrent triggering during transformer leakage spikes, allowing reliable operation under high di/dt conditions (e.g., 500V/µs). |
| Auto Restart Protection | Enters safe restart cycle on overtemperature, VCC overvoltage, open-loop, overload, or VCC undervoltage-eliminates need for external latch circuits. |
| Precise peak current limit | ±5% tolerance enables smaller transformer core selection (e.g., EF25 instead of EF30) and lower-cost secondary rectifier (e.g., 100V vs. 150V Schottky). |

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 |
|---|---|---|---|
| ICE3B2065I | 67kHz fixed switching frequency, identical RDS(on) (3.00Ω), same package and protection features | Better EMI performance at lower frequency; reduced transformer core loss but larger magnetics for same power level | Select when EMI filtering cost dominates board space, or when legacy 67kHz transformer inventory exists |
| ICE3A2065P | Same electrical specs and pinout, but PG-TO220-6-47 package with non-isolated drain tab requiring insulated heatsink mounting | Limited to low-risk consumer applications where creepage distance and isolation are not safety-critical | Select only for cost-sensitive, non-certified designs where thermal interface complexity is acceptable |
Compared with ICE3B2065I, the ICE3A2065I offers higher power density via 100kHz operation but requires tighter EMI filtering; versus ICE3A2065P, it provides safer thermal management through drain-isolation-critical for UL/EN 62368-1 certified industrial systems.

FAQ
What is the maximum continuous output power achievable with ICE3A2065I in an open-frame design?
The ICE3A2065I supports up to 50W continuous output power at Ta=50°C with RthCA=2.7K/W external heatsink, based on thermal limits (Tj≤125°C). At 230VAC ±15%, its maximum input power rating is 102W, but practical output depends on transformer efficiency, layout, and cooling-typical 50W designs achieve >88% efficiency at full load.
How does the Active Burst Mode respond to sudden load steps?
Unlike conventional burst modes with latency, ICE3A2065I's Active Burst Mode keeps the controller fully active-allowing immediate transition from burst to continuous PWM within <100 µs upon FB voltage rise. This eliminates output voltage sag or dropout during load jumps (e.g., USB-C PD negotiation), ensuring stable microcontroller operation.
Can ICE3A2065I be used without an external heatsink?
No-ICE3A2065I requires an external heatsink due to its 3.00Ω RDS(on) and 102W input power capability. In open-frame designs with RthCA=2.7K/W, it achieves 50W output at Ta=50°C. Without heatsink, junction temperature exceeds 125°C even at ~15W load, triggering thermal shutdown.
What is the function of the CS pin beyond current sensing?
The CS pin serves dual roles: it is both the current sense input (connected to source resistor) and the CoolMOS™ source terminal. This integration eliminates external source connection, but mandates Kelvin routing to avoid sensing error from PCB trace resistance-critical for maintaining ±5% current limit accuracy across temperature.
