Product details

Overview

ICE3B3065P from Infineon Technologies is an off-line SMPS current-mode controller with integrated 650V depletion CoolMOS™ and startup cell, designed for high-efficiency AC/DC flyback converters in open-frame power supplies. It delivers 128W input power at 230VAC ±15%, operates at 67kHz fixed frequency, features <±5% peak current limiting tolerance, and supports Active Burst Mode for <100mW standby power.

For engineers reviewing the ICE3B3065P datasheet, ICE3B3065P pinout, ICE3B3065P application, or ICE3B3065P equivalent, key selection criteria include its TO-220-6-47 isolated-drain package, adjustable blanking window for load-jump immunity, Auto Restart protection modes (overtemperature, overvoltage, open-loop), and precise internal PWM leading-edge blanking for EMI reduction.

Technical Context

The ICE3B3065P integrates a 650V avalanche-rugged depletion CoolMOS™ power transistor with a current-mode PWM controller in a single isolated-drain TO-220-6-47 package. Its control architecture includes a fixed 67kHz oscillator, internal soft-start, and feedback-controlled Active Burst Mode that maintains immediate load-jump response without output blackout.

Protection is implemented via Auto Restart Mode triggered by VCC undervoltage, overtemperature, output overvoltage, overload, or open-loop conditions. The device uses internal propagation delay compensation and leading-edge blanking to ensure stable current sensing across wide operating ranges, with peak current limit accuracy maintained within ±5% over temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650V - Enables direct connection to universal AC input (85–265VAC) without external HV startup resistor network.
f_SW	67kHz - Fixed switching frequency optimized for transformer size vs. EMI trade-off in mid-power flyback designs.
R_DS(on)	2.10Ω @ 25°C - Supports 128W continuous input power at 230VAC in open-frame design with R_thCA=2.7K/W heatsink.
Standby Power	<100mW - Achieved via Active Burst Mode with controller always active, eliminating output voltage dropout during light-load transitions.
Current Limit Tolerance	<±5% - Enables accurate transformer and secondary diode sizing for cost-efficient BOM without derating overhead.
Blanking Window	Adjustable - Prevents false triggering of protection or burst mode during transient high-current events like cold start or step-load jumps.
Duty Cycle Max	72% - Provides sufficient on-time margin for wide-input-range operation while maintaining safe transformer reset.

Pinout & Package

ICE3B3065P is housed in PG-TO220-6-47 - a thermally enhanced, isolated-drain TO-220 variant with creepage distance optimized for reinforced insulation in AC/DC power supplies. The drain terminal is electrically isolated from the mounting tab, enabling direct heatsink connection without additional insulation.

Pin/Terminal	Circuit Role	Design Meaning
1 (Drain)	Power MOSFET Drain	650V high-side switch node connected to primary winding; isolated from package tab for simplified heatsinking.
3 (CS)	Current Sense Input	Connects to source resistor for precise peak current detection; includes internal leading-edge blanking and propagation delay compensation.
4 (GND)	Controller Ground Reference	Analog ground for internal circuitry; separate from power ground path to minimize noise coupling into sensing loop.
5 (VCC)	Controller Supply Voltage	Internally regulated supply (7–25V range); enters undervoltage lockout below 7V with Auto Restart recovery.
6 (SoftS)	Soft-Start Control	External capacitor sets ramp time for controlled startup; prevents inrush current and overshoot during power-up.
7 (FB)	Feedback Input	Optocoupler-connected error amplifier input; controls Active Burst Mode entry/exit and regulates output voltage precision.

Key Features

Feature	Design Value
Integrated 650V CoolMOS™ + Controller	Reduces component count by eliminating external HV startup circuit and gate driver; enables compact 2-layer PCB layout.
Active Burst Mode	Maintains controller activity during no-load, ensuring sub-100mW standby while delivering immediate response to load steps without output sag.
Auto Restart Protection Suite	Single-pin fault detection (FB, VCC, CS, thermal) triggers safe shutdown with automatic recovery-no external latch or reset circuit required.
Adjustable Blanking Window	Configurable via external RC network to suppress false current-limit trips during high dv/dt transients, improving reliability in high-power flybacks.
Isolated Drain Package	Allows direct mechanical mounting to heatsink without insulating pad, reducing thermal resistance and simplifying thermal management.

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
ICE3B3065I	Same electrical specs but in PG-TO220-6-46 package with non-isolated drain; requires insulated mounting pad.	Lower-cost heatsink integration where reinforced creepage is not required (e.g., non-medical consumer products).	Select when thermal performance priority outweighs isolation requirements and board-level creepage can be managed externally.
ICE3B2065P	Lower R_DS(on) (3.00Ω) limits max input power to 102W at 230VAC; identical pinout and protection features.	Suitable for 50–65W applications where lower peak power demand allows reduced heatsink size and cost.	Choose for cost-sensitive mid-power designs where 128W headroom is unnecessary and thermal budget is tighter.

Compared with ICE3B3065I, the ICE3B3065P offers superior isolation safety and simplified thermal design; versus ICE3B2065P, it delivers +25W power capability at identical footprint and protection functionality-enabling scalable platform design across 65W–128W product tiers.

FAQ

What is the maximum continuous input power rating for ICE3B3065P?

The ICE3B3065P supports up to 128W continuous input power at 230VAC ±15% in an open-frame design with external heatsink (R_thCA = 2.7K/W) at T_a = 50°C and T_j = 125°C. This rating assumes proper PCB copper area and thermal interface material; derating applies above 50°C ambient.

Does ICE3B3065P require an external startup resistor?

No. ICE3B3065P integrates a 650V startup cell that draws current directly from the rectified AC line through the drain pin, eliminating the need for an external high-voltage startup resistor and associated power loss during normal operation.

How does the adjustable blanking window improve system reliability?

The adjustable blanking window suppresses false current-limit triggering during high dv/dt events-such as transformer leakage spikes or cold-start surges-by temporarily disabling the current-sense comparator. This prevents unintended Auto Restart Mode activation and ensures stable operation under dynamic load conditions.

Can ICE3B3065P be used in medical-grade power supplies?

Yes-when implemented with appropriate isolation barriers, creepage/clearance layout, and safety-certified transformers. Its PG-TO220-6-47 package provides ≥8mm creepage, and Auto Restart Mode supports fail-safe behavior. However, final medical certification requires full system-level validation per IEC 60601-1.
