Product details

Overview

ICE3B3065PBKSA1 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 128W continuous input power at 230VAC ±15%, operates at fixed 67kHz switching frequency, features active burst mode for <100mW standby power, and provides precise peak current limiting with <±5% tolerance-used in universal-input flyback SMPS for consumer adapters and industrial power supplies.

For engineers reviewing the ICE3B3065PBKSA1 datasheet, ICE3B3065PBKSA1 pinout, ICE3B3065PBKSA1 application, or ICE3B3065PBKSA1 equivalent, key selection criteria include its integrated 650V CoolMOS™, auto-restart protection modes (overtemperature, overvoltage, open-loop), adjustable blanking window for load-jump immunity, and isolated drain package enabling simplified heatsinking in high-voltage primary-side regulation.

Technical Context

The ICE3B3065PBKSA1 integrates a current-mode PWM controller and 650V depletion CoolMOS™ in a single isolated-drain TO-220 package, eliminating external high-voltage startup resistors and reducing component count. Its control architecture includes internal oscillator (67kHz), leading-edge blanking, propagation delay compensation, and soft-start via external capacitor on SoftS pin.

Protection is implemented via Auto Restart Mode triggered by VCC undervoltage, overtemperature, output overvoltage, overload, or open-loop conditions-each forcing controlled shutdown and periodic restart attempts. The feedback loop accepts optocoupler-derived signals on FB pin to regulate output voltage while maintaining stable operation across wide line and load ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650V - avalanche-rugged drain rating enables direct rectified mains connection without external clamping in universal-input (85–265VAC) flyback designs
f_SW	67kHz - fixed-frequency operation simplifies EMI filter design and transformer core selection for 128W continuous input power
R_DS(on)	2.10Ω @ T_j=25°C - low conduction loss supports 62W output power at T_a=50°C with R_thCA=2.7K/W heatsink
I_peak limit tol.	±5% - tight current-sense accuracy reduces transformer oversizing and improves cross-regulation in multi-output converters
Standby power	<100mW - achieved via Active Burst Mode with immediate load-jump response, eliminating output voltage blackout during light-to-heavy transitions
Startup cell	Integrated 650V depletion CoolMOS™ - eliminates external high-voltage resistor network, reducing BOM count and improving reliability
Protection modes	Auto Restart for VCC UVLO, overtemperature, overvoltage, overload, open-loop - ensures fail-safe behavior without latching shutdown

Pinout & Package

ICE3B3065PBKSA1 uses the PG-TO220-6-47 package: isolated drain tab (pin 1), electrically separated from internal controller ground; pins 3–7 are signal terminals mounted on insulated leadframe; creepage distance optimized for reinforced insulation in 230VAC applications.

Pin/Terminal	Circuit Role	Design Meaning
1 Drain	650V CoolMOS™ drain terminal	High-voltage switching node connected to primary winding; isolated metal tab enables direct heatsinking without insulating pad
3 CS	Current sense input	Connects to source resistor for peak-current-mode control; includes internal leading-edge blanking (500ns typical)
4 GND	Controller ground reference	Low-noise analog/digital ground for internal circuitry; separate from power ground path to minimize noise coupling
5 VCC	Controller supply input	Accepts 11.5–25V DC; powers internal logic and gate driver; includes UVLO with hysteresis (10.5V turn-on / 9.5V turn-off)
6 SoftS	Soft-start timing input	External capacitor sets ramp time for duty cycle; prevents inrush current during startup and stabilizes initial regulation
7 FB	Feedback error amplifier input	Receives optocoupler signal to adjust duty cycle; high-impedance input (1μA max) minimizes loading on secondary-side regulation circuit

Key Features

Feature	Design Value
Active Burst Mode	Enables immediate load-step response with <1% output ripple at no-load, eliminating blackouts during light-to-heavy transitions
Adjustable blanking window	Configurable via external resistor to suppress false triggering during high di/dt events (e.g., transformer leakage spikes)
Isolated drain package	PG-TO220-6-47 allows direct mounting to heatsink without thermal pad or isolation washer, reducing thermal resistance by ~1.2K/W
Precise current limiting	±5% tolerance over temperature ensures consistent power delivery and enables smaller magnetics without derating
Auto Restart protection	Non-latching fault recovery for VCC UVLO, overtemperature, overvoltage, overload, and open-loop conditions enhances field reliability

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 die, PG-TO220-6-46 package with non-isolated drain tab requiring insulating pad for heatsinking	Lower creepage distance; suitable only where reinforced insulation is not mandated	Select when cost-sensitive designs allow standard isolation practices and thermal pad usage

FAQ

What is the maximum continuous output power achievable with ICE3B3065PBKSA1 in an open-frame design?

At 230VAC ±15% input and T_a=50°C with R_thCA=2.7K/W external heatsink, ICE3B3065PBKSA1 supports up to 62W continuous output power. This rating assumes proper PCB copper area, adequate airflow, and correct transformer design per Infineon Application Note AN2013-04. Derating applies above 50°C ambient or with reduced heatsinking.

How does the Active Burst Mode differ from conventional burst mode in terms of load-step response?

Unlike conventional burst mode that disables the controller between bursts, ICE3B3065PBKSA1's Active Burst Mode keeps the internal oscillator and control logic continuously powered-enabling immediate duty-cycle adjustment within one switching cycle upon load increase. This eliminates output voltage dropout and maintains <1% ripple even during 0%→100% load steps.

Can the blanking window be adjusted externally, and what is its functional range?

Yes, the blanking window duration is set by an external resistor connected between SoftS pin and GND. It is adjustable from 200ns to 1.2μs, allowing optimization for different transformer leakage inductance and snubber configurations. Values outside this range may cause missed current peaks or false overcurrent trips.

Does ICE3B3065PBKSA1 require an external bootstrap capacitor or high-side driver for gate control?

No-ICE3B3065PBKSA1 integrates a self-supplied gate driver with internal charge pump, eliminating need for external bootstrap components. The CoolMOS™ gate is driven directly from the controller's output stage, with soft-switching characteristics optimized to reduce EMI and gate oscillation without external RC networks.
