Product details

Overview

ICE3A5565PBKSA1 from Infineon Technologies is a 650V off-line SMPS current-mode controller IC integrating a depletion-mode CoolMOS™ power transistor and high-voltage startup cell in a PG-TO220-6-47 package. It delivers 240W input power at 230VAC ±15%, operates at 100kHz fixed frequency, features <±5% peak current limiting tolerance, and supports Active Burst Mode for <100mW standby power in AC/DC adapters and open-frame power supplies.

For engineers reviewing the ICE3A5565PBKSA1 datasheet, ICE3A5565PBKSA1 pinout, ICE3A5565PBKSA1 application, or ICE3A5565PBKSA1 equivalent, key selection criteria include its integrated 650V CoolMOS™ with R_DS(on) = 0.79Ω (T_j = 25°C), Auto Restart protection modes (overtemperature, overvoltage, overload, VCC UVLO), adjustable blanking window, and isolated drain package enabling reinforced insulation in Class II designs.

Technical Context

The ICE3A5565PBKSA1 implements a current-mode PWM control architecture with internal oscillator set to 100kHz, precise leading-edge blanking, and propagation delay compensation for stable peak-current sensing across load transients. Its integrated CoolMOS™ enables direct high-voltage switching without external gate drivers or startup resistors.

Control logic includes dedicated SoftS pin for user-defined soft-start timing, FB pin for optocoupler-based voltage regulation, and CS pin that senses both current-limit threshold and CoolMOS™ source voltage-enabling accurate cycle-by-cycle current limiting and short-circuit protection via Auto Restart Mode.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650V rated drain-source voltage - supports universal AC input (85–265VAC) with margin for surge and line transients
f_SW	100kHz fixed switching frequency - balances EMI performance and transformer size for mid-to-high power SMPS
R_DS(on)	0.79Ω @ T_j = 25°C - enables 240W continuous input power at 230VAC in open-frame design with R_thCA = 2.7K/W
Current Limit Tolerance	<±5% overall - reduces transformer and secondary diode derating requirements, lowering BOM cost
Standby Power	<100mW @ no load - achieved via Active Burst Mode with immediate load-jump response and <1% output ripple
Protection Modes	Auto Restart for overtemperature, VCC overvoltage, output open-loop, overload, and VCC undervoltage - eliminates latch-off failures in field-deployed systems
Blanking Window	User-adjustable - prevents false triggering during high di/dt events (e.g., cold start, step-load), improving reliability

Pinout & Package

ICE3A5565PBKSA1 uses the PG-TO220-6-47 package: isolated drain tab (pin 1), internal heatsink-connected drain, creepage-optimized layout for reinforced insulation, RoHS-compliant Pb-free plating, and TO-220 footprint compatibility.

Pin/Terminal	Circuit Role	Design Meaning
1 Drain	CoolMOS™ high-side switch drain terminal	Connected to primary winding hot side; electrically isolated from package tab for enhanced safety isolation
3 CS	Current sense / CoolMOS™ source node	Provides cycle-by-cycle current limiting input and CoolMOS™ source reference; enables precise R_SENSE-based protection
4 GND	Controller ground reference	Low-noise analog/digital ground return for internal circuitry; separate from power ground path
5 VCC	Internal controller supply input	Powered by integrated 650V startup cell; regulated internally to 14.5V; UVLO threshold at 9.5V
6 SoftS	Soft-start timing control	External capacitor sets ramp time for controlled V_REF rise, preventing inrush current and transformer saturation
7 FB	Feedback error amplifier input	Receives optocoupler signal for secondary-side voltage regulation; controls duty cycle via PWM latch reset

Key Features

Feature	Design Value
Integrated 650V CoolMOS™ + controller	Eliminates external HV startup resistor and gate driver; reduces component count by ≥4 vs. discrete solutions
Active Burst Mode	Delivers <100mW standby power while maintaining real-time load responsiveness-no black-out during light-to-heavy load transitions
Precise peak current limiting	<±5% tolerance enables smaller transformer core and lower-cost secondary rectifier without compromising safety margins
Adjustable blanking window	Prevents false overcurrent trips during high di/dt events (e.g., cold start, step load), increasing system robustness
Auto Restart protection suite	Covers overtemperature, VCC overvoltage, output open-loop, overload, and VCC undervoltage-ensures fail-safe recovery without manual reset

FAQ

What is the maximum continuous input power rating for ICE3A5565PBKSA1?

The ICE3A5565PBKSA1 supports up to 240W continuous input power at 230VAC ±15% in an open-frame design with ambient temperature T_a = 50°C, junction temperature T_j = 125°C, and external heatsink thermal resistance R_thCA = 2.7K/W. This rating assumes proper PCB copper area and airflow per Infineon's thermal guidelines in Version 2.3 datasheet Section 5.

Does ICE3A5565PBKSA1 require an external startup resistor?

No. ICE3A5565PBKSA1 integrates a 650V startup cell that draws current directly from the rectified AC line, eliminating the need for an external high-voltage startup resistor. The internal startup circuit charges the VCC capacitor until the controller reaches its 9.5V UVLO threshold, after which the CoolMOS™ begins switching and sustains VCC via auxiliary winding.

How does the adjustable blanking window improve system reliability?

The blanking window disables current-sense comparator input for a user-defined duration after each PWM pulse edge, preventing false overcurrent detection during transformer leakage inductance spikes or MOSFET turn-on transients. This avoids unnecessary Auto Restart entries during high di/dt events like cold start or step-load, preserving system uptime and reducing stress on magnetics.

Can ICE3A5565PBKSA1 be used in Class II (double-insulated) applications?

Yes. The PG-TO220-6-47 package provides isolated drain construction with reinforced creepage distance between drain and other pins, meeting IEC 60950-1 and IEC 62368-1 requirements for Class II isolation. No additional isolation barrier is needed between primary and secondary sides when layout follows Infineon's creepage/clearance recommendations in the datasheet.
