Product details

Overview

ICE3A1065ELJ from Infineon Technologies is an integrated off-line SMPS current-mode controller combining a 650V avalanche-rugged CoolMOS® power transistor, startup cell, and control logic in a single PG-DIP-8 package. It delivers 32W maximum input power at 230VAC ±15%, operates at a fixed 100kHz switching frequency, features active burst mode for <100mW standby power, and includes latched-off protection for overvoltage, overtemperature, and short winding faults - deployed in auxiliary power supplies and set-top box adapters.

For engineers reviewing the ICE3A1065ELJ datasheet, ICE3A1065ELJ pinout, ICE3A1065ELJ application, or ICE3A1065ELJ equivalent, key selection criteria include its integrated 650V CoolMOS®, 75% max duty cycle, ±5% current limit tolerance, built-in soft start (20ms), and system-noise robustness validated under ESD/lightning surge testing.

Technical Context

The ICE3A1065ELJ implements a BiCMOS-based current-mode PWM architecture with propagation delay compensation and internal leading-edge blanking (220ns). Its control unit integrates dual blanking modes - fixed 20ms basic and extendable via external capacitor on BL pin - to suppress false overload detection during transient load jumps.

It embeds a high-voltage startup cell connected directly to the Drain terminal, eliminating the need for an external startup resistor. The IC enters active burst mode under light load, maintaining optocoupler-based secondary-side regulation while minimizing V_OUT ripple and enabling full-cycle control without external RC filtering in the feedback path.

Key Specifications

Parameter	Value and Actual Design Meaning
Switching Frequency	100kHz fixed - enables predictable EMI filter design and consistent transformer sizing.
Integrated MOSFET V_DSS	650V - supports universal AC input (85–265VAC) with margin for surge and line transients.
Max Input Power	32W at 230VAC ±15%, T_a=75°C - defines usable output capability without heatsink copper area.
Current Limit Tolerance	±5% - ensures precise overcurrent protection across temperature and process variation.
Standby Power	<100mW in Active Burst Mode - meets stringent EU CoC Tier 2 and DOE Level VI requirements.
V_CC Operating Range	10.5V to 26V - accommodates wide auxiliary supply variation and simplifies bias winding design.
Soft Start Time	20ms - prevents inrush current stress on primary switch and bulk capacitor during power-up.

Pinout & Package

ICE3A1065ELJ is housed in a PG-DIP-8 package with creepage/clearance optimized for reinforced insulation in off-line applications. Pins 4 and 5 are internally shorted as a single Drain connection; Pin 6 is unconnected (n.c.).

Pin/Terminal	Circuit Role	Design Meaning
1 BL	Blanking & External Latch Enable	Extends 20ms blanking window via external capacitor; pulls <0.1V to trigger immediate latch-off.
2 FB	Optocoupler Feedback Input	Directly interfaces secondary-side error amplifier; controls duty cycle and activates Active Burst Mode.
3 CS	Current Sense Input	Monitors source voltage of integrated CoolMOS®; triggers shutdown when threshold (typ. 1.35V) is exceeded.
4 & 5 Drain	CoolMOS® Drain Terminal	High-side switching node; rated for 650V; pins internally shorted for current sharing and thermal relief.
6 n.c.	No Connection	Not bonded; must remain floating - no PCB trace or component connection permitted.
7 VCC	Controller Supply Input	Accepts 10.5–26V; powers internal circuitry; UVLO thresholds at 6.23V (reset) and 18V (startup cell disable).
8 GND	Controller Ground Reference	Low-impedance return for control logic and current sense comparator; separate from power ground in layout.

Key Features

Feature	Design Value
Integrated 650V CoolMOS® + Startup Cell	Eliminates external HV startup resistor; reduces BOM count and improves light-load efficiency.
Active Burst Mode with Opto Control	Maintains closed-loop regulation via same optocoupler during standby - no secondary-side redesign needed.
Extendable Blanking Window	20ms base + external capacitor on BL pin - prevents nuisance tripping during dynamic load steps.
Frequency Jitter & Soft Driving	Reduces peak EMI amplitude by spreading spectral energy; eases compliance with CISPR 22/32 Class B.
System Noise Robustness	Validated against ESD (IEC 61000-4-2), lightning surge (IEC 61000-4-5), and fast transient bursts.

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
ICE3A1065JZ	Same F3 platform but LJ version - lacks ELJ's enhanced system-noise immunity and extended blanking flexibility.	Lower cost for non-surge-critical applications; not qualified for lightning surge (IEC 61000-4-5) environments.	Select when ESD/surge robustness is not required and BOM cost is prioritized over design margin.
ICE2QS03G	Quasi-resonant controller with external MOSFET; no integrated HV switch; lower standby power (~50mW) but higher component count.	Better efficiency above 50% load; requires external gate driver, startup resistor, and current sense network.	Select when highest light-load efficiency is mandatory and board space allows additional discrete components.

Compared with ICE3A1065JZ and ICE2QS03G, the ICE3A1065ELJ uniquely balances integration (650V CoolMOS®, startup cell), noise resilience (ESD/surge-hardened), and regulatory compliance (<100mW standby) in a single DIP-8 footprint - ideal for cost-sensitive, safety-critical auxiliary supplies.

FAQ

What is the purpose of the BL pin on ICE3A1065ELJ?

The BL pin serves two distinct functions: it extends the internal 20ms blanking window via an external capacitor to suppress false overload detection during load transients, and it enables external latch-off by pulling the pin below 0.1V - triggering immediate shutdown for system-level fault handling independent of internal sensing.

Does ICE3A1065ELJ require an external startup resistor?

No. ICE3A1065ELJ integrates a high-voltage startup cell connected directly to the Drain pin, eliminating the need for an external startup resistor. This cell automatically disables once V_CC exceeds 18V, reducing no-load losses and improving light-load efficiency without added components.

How does Active Burst Mode maintain regulation in ICE3A1065ELJ?

Active Burst Mode retains full optocoupler-based feedback control - the FB pin continues to monitor secondary-side output voltage and modulate burst frequency and pulse width. Unlike conventional burst modes, it avoids output voltage droop and maintains tight regulation (<±5%) even at sub-100mW loads.

What is the maximum continuous output power achievable with ICE3A1065ELJ?

At 230VAC ±15% input, ambient temperature of 75°C, and junction temperature limited to 125°C without heatsink copper area, ICE3A1065ELJ supports up to 32W maximum input power - translating to ~25W typical continuous output power depending on topology efficiency and thermal design.
