Product details
Overview
ICE3B2065P-2 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-TO220-6-47 package. It delivers 102W input power at 230VAC ±15%, operates at fixed 67kHz switching frequency, features ±5% peak current limit tolerance, and supports Active Burst Mode for <100mW standby power in auxiliary power supplies.
For engineers reviewing the ICE3B2065P-2 datasheet, ICE3B2065P-2 pinout, ICE3B2065P-2 application, or ICE3B2065P-2 equivalent, key selection criteria include its integrated high-voltage switch, auto-restart protection suite (overtemperature, overvoltage, open-loop), adjustable blanking window for load-jump immunity, and isolated drain package enabling simplified heatsinking in universal-input SMPS designs.
Technical Context
The ICE3B2065P-2 implements a current-mode control architecture with internal oscillator set to 67kHz, precise leading-edge blanking, and propagation delay compensation for stable peak-current sensing. Its integrated 650V CoolMOS™ enables direct connection to rectified mains without external HV startup resistor.
Control logic includes dedicated SoftS pin for user-defined soft-start timing, FB pin for optocoupler-based voltage regulation, and CS pin that serves dual role as current sense input and CoolMOS™ source terminal. Auto Restart Mode triggers on VCC undervoltage, overtemperature, output overvoltage, or overload conditions - all implemented via internal thermal shutdown and fault latching circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | Fixed 67 kHz - enables predictable EMI filtering and transformer design with minimal external timing components. |
| Max Input Power (230VAC) | 102 W - defines maximum continuous output capability in open-frame design at Ta=50°C, Tj=125°C, RthCA=2.7K/W. |
| Peak Current Limit Tolerance | ±5% - ensures consistent transformer sizing and secondary diode selection across production lots. |
| Standby Power | <100 mW in Active Burst Mode - meets stringent no-load efficiency requirements for Energy Star and EU CoC Tier 2 compliance. |
| CoolMOS™ VDS | 650 V - supports universal AC input (85–265 VAC) with margin for surge and line transients. |
| Duty Cycle Limit | 72% - constrains maximum on-time to prevent transformer saturation under low-line, high-load conditions. |
| Startup Cell | Integrated 650V depletion-mode startup - eliminates external HV resistor, reducing BOM count and board space. |
Pinout & Package
ICE3B2065P-2 uses PG-TO220-6-47 package: isolated drain tab (pins 1 & 2 internally connected), plastic body, 6-pin leadframe with pin 1 = Drain, pin 2 = Drain (shorted), pin 3 = CS, pin 4 = GND, pin 5 = VCC, pin 6 = SoftS, pin 7 = FB. The drain-isolated construction allows direct mounting to heatsink without insulator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 Drain | CoolMOS™ high-side switch drain | Directly connects to rectified AC input; electrically isolated from package tab for safe heatsink mounting. |
| 3 CS | Current sense / CoolMOS™ source | Provides primary-side current feedback; 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 circuits; separate from power ground path. |
| 5 VCC | Internal regulator input & supply | Receives bias from auxiliary winding; internal LDO powers control logic after startup. |
| 6 SoftS | Soft-start timing control | External capacitor sets ramp time for PWM duty cycle during power-up to limit inrush current. |
| 7 FB | Feedback error amplifier input | Accepts optocoupler signal to regulate output voltage; controls burst mode entry/exit and PWM duty. |
Key Features
| Feature | Design Value |
|---|---|
| Active Burst Mode | Enables immediate load-step response with <1% output ripple at light load - avoids blackouts common in traditional burst modes. |
| Adjustable Blanking Window | User-configurable via external RC network to suppress false overcurrent trips during transient load jumps. |
| Auto Restart Protection | Self-resetting recovery from overtemperature, VCC overvoltage, open-loop, overload, and undervoltage faults - improves field reliability. |
| Integrated Startup Cell | 650V depletion CoolMOS™ eliminates need for external HV startup resistor - reduces component count and leakage paths. |
| Precise Peak Current Limit | ±5% tolerance ensures consistent power delivery and simplifies transformer design across temperature and process variation. |

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 | Same electrical specs but PG-TO220-6-46 package with different pin 1–2 spacing and non-isolated drain tab. | Requires insulating pad when mounted to shared heatsink; lower creepage distance limits use in reinforced insulation designs. | Select ICE3B2065I only if mechanical footprint matches legacy I2Pak layout and isolation requirements permit. |
| ICE3B2065 | PG-DIP-8 package variant with pins 4/5 shorted internally; no isolated drain; lower power rating (57W @ 230VAC). | Suitable for lower-power consumer adapters where board-level isolation suffices and heatsinking is via PCB copper. | Choose ICE3B2065 for cost-sensitive, space-constrained designs below 60W where TO220 mounting is not required. |
Compared with ICE3B2065I and ICE3B2065, the ICE3B2065P-2 uniquely combines TO220-6-47's isolated drain, 102W power capability, and creepage-compliant layout - making it the sole option for high-reliability industrial SMPS requiring direct heatsink mounting without insulation.

FAQ
What is the purpose of the SoftS pin on ICE3B2065P-2?
The SoftS pin accepts an external capacitor to control the soft-start ramp time, limiting inrush current during power-up by gradually increasing PWM duty cycle. This prevents transformer saturation and stress on bulk capacitors, especially critical in high-power universal-input designs where input voltage range spans 85–265 VAC.
How does the Active Burst Mode differ from conventional burst mode in ICE3B2065P-2?
Unlike conventional burst modes that disable the controller between bursts, ICE3B2065P-2 remains fully active during Active Burst Mode - enabling immediate response to load steps without output dropout. This results in <1% output voltage ripple at light load and eliminates blackouts in sensitive applications like smart home gateways.
Can ICE3B2065P-2 operate without an auxiliary winding for VCC supply?
No - ICE3B2065P-2 requires an auxiliary winding to supply VCC after startup. The integrated 650V startup cell provides initial bias only until the auxiliary winding generates sufficient voltage; thereafter, the internal LDO regulates VCC from the auxiliary source. Omitting the auxiliary winding causes VCC undervoltage lockout and repeated auto-restart cycles.
What is the significance of the isolated drain in PG-TO220-6-47 package?
The isolated drain in PG-TO220-6-47 means the metal tab (drain) is electrically insulated from the leadframe, allowing direct mounting to a grounded heatsink without additional insulators. This simplifies thermal design, improves reliability in high-voltage applications, and meets creepage/clearance requirements for reinforced insulation per IEC 62368-1.
