Product details

Overview

ICE3A5065PBKSA1 from Infineon Technologies is a current-mode off-line SMPS controller integrating a 650V depletion CoolMOS™ power transistor and startup cell in a single PG-TO220-6-47 package. It delivers 220W input power at 230VAC ±15%, operates at 100kHz fixed frequency, features 0.95Ω R_DS(on) (T=25°C), and supports Active Burst Mode for <100mW standby power.

For engineers reviewing the ICE3A5065PBKSA1 datasheet, ICE3A5065PBKSA1 pinout, ICE3A5065PBKSA1 application, or ICE3A5065PBKSA1 equivalent, key selection criteria include integrated high-voltage switching capability, precise ±5% peak current limiting, adjustable blanking window for load-jump immunity, and Auto Restart protection modes for overtemperature, overvoltage, overload, and VCC undervoltage conditions.

Technical Context

The ICE3A5065PBKSA1 implements a fixed-frequency (100kHz) current-mode PWM control architecture with internal oscillator, leading-edge blanking, and propagation delay compensation to ensure accurate current sensing under fast transient conditions. Its integrated 650V depletion CoolMOS™ enables direct AC/DC primary-side switching without external HV startup resistors.

Control logic includes an Active Burst Mode triggered by feedback voltage level, enabling immediate response to load steps while maintaining <1% output ripple. Protection is implemented via Auto Restart Mode across five fault conditions-overtemperature, VCC overvoltage, open-loop, overload, and VCC undervoltage-with dedicated internal detection circuits and latch-free recovery.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650V - Enables direct connection to universal AC input (85–265VAC) without external HV startup network.
f_SW	100kHz - Fixed switching frequency simplifies EMI filter design and transformer sizing for mid-to-high power SMPS.
R_DS(on)	0.95Ω @ T=25°C - Supports 220W continuous input power at 230VAC in open-frame design with external heatsink (R_thCA=2.7K/W).
Current Limit Tolerance	±5% - Enables precise transformer and secondary diode sizing for cost-optimized, thermally robust designs.
Standby Power	<100mW - Achieved via Active Burst Mode with immediate wake-up on load step, eliminating output blackout.
Max Duty Cycle	72% - Provides sufficient conduction time margin for flyback and forward converter topologies under worst-case line and load.
Blanking Window	Adjustable - Prevents false triggering of current-limit protection during high di/dt events like output short-circuit recovery.

Pinout & Package

ICE3A5065PBKSA1 uses the PG-TO220-6-47 package: isolated drain tab, 6-pin through-hole mounting, RoHS-compliant lead plating, and wide creepage distance suitable for reinforced insulation in AC/DC converters up to 300W.

Pin/Terminal	Circuit Role	Design Meaning
1 (Drain)	High-voltage power switch drain	Directly connects to primary winding of flyback/forward transformer; rated for 650V avalanche rugged operation.
3 (CS)	Current sense input	Monitors source current of integrated CoolMOS™; feeds internal PWM comparator with leading-edge blanking enabled.
4 (GND)	Controller ground reference	Low-noise analog/digital ground return for internal circuitry; separate from power ground path in layout best practice.
5 (VCC)	Controller supply input	Accepts 10.5–25V DC; powers internal logic and gate driver; includes undervoltage lockout (UVLO) with hysteresis.
6 (SoftS)	Soft-start timing node	Connects external capacitor to set ramp-up time for duty cycle; prevents inrush current and overshoot at startup.
7 (FB)	Feedback error amplifier input	Receives optocoupler signal from secondary side; controls burst mode entry/exit and regulates output voltage precision.

Key Features

Feature	Design Value
Integrated 650V CoolMOS™ + controller	Eliminates external HV startup resistor and discrete MOSFET, reducing BOM count and PCB area in offline SMPS.
Active Burst Mode	Delivers <100mW no-load standby power while maintaining real-time responsiveness to load transients-no black-out period.
Precise ±5% peak current limit	Enables tighter transformer turns ratio tolerance and smaller secondary rectifier selection without derating.
Auto Restart protection suite	Five independent fault responses (OTP, OVP, OLP, OL, UVLO) reset automatically after fault clearance-no manual intervention needed.
Adjustable blanking window	Configurable via external RC network to suppress false current-limit trips during high di/dt events like output short recovery.

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
ICE3A5065IBKSA1	Same electrical specs but in PG-TO220-6-46 (I2Pak) package with isolated drain tab and different mechanical outline.	Requires different heatsink mounting geometry; identical thermal performance when mounted per datasheet guidelines.	Select ICE3A5065IBKSA1 only if legacy board layout or heatsink interface matches I2Pak footprint.
ICE3B5065PBKSA1	Identical package and R_DS(on), but 67kHz switching frequency and lower EMI generation at expense of larger magnetics.	Better suited for EMI-sensitive medical or audio applications where switching noise must be minimized below 100kHz.	Choose ICE3B5065PBKSA1 when EMI compliance drives frequency selection over power density.

Compared with ICE3A5065IBKSA1 and ICE3B5065PBKSA1, ICE3A5065PBKSA1 offers optimal balance of power density (100kHz), thermal performance (TO220-6-47), and design flexibility (adjustable blanking), making it preferred for space-constrained industrial and consumer SMPS where rapid load response is critical.

FAQ

What is the maximum continuous input power rating for ICE3A5065PBKSA1?

The ICE3A5065PBKSA1 supports up to 220W continuous input power at 230VAC ±15% in an open-frame design with external heatsink (R_thCA = 2.7K/W), ambient temperature of 50°C, and junction temperature limited to 125°C. This rating assumes proper PCB copper area and thermal interface material per Infineon's layout guidelines in the datasheet.

Does ICE3A5065PBKSA1 require an external startup resistor?

No. ICE3A5065PBKSA1 integrates a 650V startup cell that draws initial current directly from the rectified AC line, eliminating the need for external high-voltage startup resistors. The device begins operation once VCC reaches the turn-on threshold (~14.5V), after which it is self-supplied via auxiliary winding.

How does the adjustable blanking window function in ICE3A5065PBKSA1?

The blanking window is configured using an external RC network on the SoftS pin. It disables the current-sense comparator for a user-defined duration after each PWM pulse edge, preventing false triggering during transformer leakage spikes or output short-circuit recovery. This improves system reliability under high di/dt conditions without compromising protection speed.

Can ICE3A5065PBKSA1 be used in medical equipment power supplies?

Yes-subject to Infineon's formal written approval for life-support applications. The device meets IEC 62368-1 reinforced insulation requirements due to its isolated drain package and wide creepage distance. Its Auto Restart Mode provides fail-safe behavior during VCC overvoltage or open-loop faults, supporting auxiliary power functions in certified medical systems.
