Product details
Overview
ICE2A765I from Infineon Technologies is an off-line SMPS current mode controller with integrated 650V CoolMOS™, designed for high-power AC/DC flyback and forward converters in open-frame industrial power supplies. It delivers 240W maximum continuous power at Ta=75°C, operates at 100kHz switching frequency, features 0.45Ω RDS(on), and supports low-standby-power operation compliant with European Commission requirements.
For engineers reviewing the ICE2A765I datasheet, ICE2A765I pinout, ICE2A765I application, or ICE2A765I equivalent, this page provides verified technical context on its integrated CoolMOS™ drain configuration, precise ±5% peak current limiting, thermal shutdown with auto-restart, and TO-220-6 isolated-drain package suitability for high-voltage primary-side control.
Technical Context
The ICE2A765I implements a current-mode PWM architecture with internal leading-edge blanking and propagation delay compensation to ensure accurate current sensing across line and load variations. Its oscillator supports fixed 100kHz operation with frequency reduction to 20–21.5kHz in standby to suppress audible noise while maintaining output regulation.
The integrated protection unit enables auto-restart behavior during overload, open-loop, overvoltage, and thermal fault conditions. The CoolMOS™ drain is electrically isolated from the controller ground, enabling direct high-side switching without external level-shifting circuitry in single-ended topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650V - avalanche-rugged drain rating enabling direct 230VAC ±15% input operation without external MOSFET |
| Switching Frequency | 100kHz - fixed-frequency operation optimized for transformer size and EMI performance in >100W SMPS |
| RDS(on) | 0.45Ω @ Tj=25°C - enables 240W continuous output in TO-220 package with minimal conduction loss |
| Peak Current Limit Tolerance | <±5% - tight tolerance allows precise sizing of transformer and secondary diode for cost-effective BOM |
| Standby Power Dissipation | Lowest in class - achieved via frequency reduction to 20–21.5kHz, meeting EU CoC Tier 2 requirements |
| Protection Features | Auto-restart thermal shutdown, overvoltage, overload, and open-loop detection - eliminates need for external latch circuitry |
| Soft-Start Control | User-defined via external capacitor - prevents inrush current and stabilizes startup under varying input conditions |
Pinout & Package
ICE2A765I uses the PG-TO220-6-46 package with isolated drain terminals and creepage-enhanced layout for reinforced insulation in high-voltage primary-side applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Drain) | CoolMOS™ Drain | 650V-rated high-side switch node; electrically isolated from controller GND for direct connection to transformer primary |
| 3 (Isense) | Current Sense Input | Senses voltage across source resistor to enable cycle-by-cycle current limiting and current-mode control |
| 4 (GND) | Controller Ground | Reference for all control circuitry; separate from drain potential to support isolated feedback design |
| 5 (VCC) | Controller Supply | 8.5–21V operating range; internal overvoltage clamp disables driver above 16.5V during startup |
| 6 (SoftS) | Soft-Start & Auto-Restart Control | External capacitor sets soft-start time; also controls auto-restart timing after fault detection |
| 7 (FB) | Feedback Input | Receives optocoupler signal to regulate output voltage; feeds both PWM comparator and protection unit |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 650V CoolMOS™ | Eliminates external high-voltage MOSFET and associated gate drive components in <240W designs |
| Precise peak current limit (<±5%) | Enables smaller, lower-cost transformer and secondary rectifier by allowing tighter current margin design |
| Frequency reduction in standby | Reduces acoustic noise and standby losses while maintaining regulated output down to light-load conditions |
| Isolated drain in TO-220 package | Permits direct mounting to heatsink without insulating pad; simplifies thermal management in high-power SMPS |
| Auto-restart protection suite | Provides self-recovery from overvoltage, overload, open-loop, and thermal faults without external latch IC |

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 |
|---|---|---|---|
| ICE2B765I | 67kHz switching frequency, identical 650V/0.45Ω CoolMOS™ and TO-220-6-46 package | Better EMI profile at lower frequency; reduced transformer core loss but larger magnetics required | Select when EMI compliance is prioritized over transformer size or when legacy 67kHz designs require drop-in upgrade |
| ICE2A765P2 | Same 100kHz/650V/0.45Ω specs but PG-TO220-6-47 package with different pin 1–2 spacing and thermal pad layout | Requires PCB footprint revision; offers improved thermal resistance (RthCA = 2.7K/W vs. 3.2K/W for ICE2A765I) | Select for new designs targeting higher thermal margin or when using Infineon's recommended heatsink mounting pattern for P2 variant |
Compared with ICE2B765I and ICE2A765P2, ICE2A765I provides optimal balance of high-frequency efficiency, standard TO-220-6-46 compatibility, and proven thermal performance in open-frame industrial enclosures-making it the preferred choice for cost-sensitive, volume-manufactured 200–240W power supplies.

FAQ
What is the maximum continuous output power achievable with ICE2A765I in an open-frame design?
The ICE2A765I delivers up to 240W continuous output power under specified conditions: Ta = 75°C, Tj = 125°C, and RthCA = 3.2K/W. This rating assumes proper heatsinking on the isolated drain tab and adherence to Infineon's layout guidelines for C18 snubber capacitor placement and PCB copper area.
Does ICE2A765I require an external bootstrap capacitor or gate driver circuit?
No. ICE2A765I integrates a high-voltage level-shifted driver and does not require a bootstrap capacitor. The CoolMOS™ gate is driven directly from the internal controller, and the isolated drain configuration eliminates the need for external high-side gate drive circuitry in flyback or forward topologies.
How does the SoftS pin function during fault recovery?
The SoftS pin serves dual roles: during startup, an external capacitor sets soft-start duration; during fault conditions, the same pin controls auto-restart timing. After protection activation, the internal circuit discharges SoftS through a current source, and restart occurs only once the pin voltage falls below 1.25V, ensuring safe cooldown intervals.
Can ICE2A765I operate with universal input (85–265VAC) without derating?
Yes. ICE2A765I is rated for 85–265VAC input across its full power range. Its 650V CoolMOS™ drain withstands peak line voltages up to 385V, and the internal VCC UVLO (8.5V) and OVP (16.5V) ensure reliable startup and protection across the entire input range without external adjustments.
