Product details

Overview

ICE3AR10080JZTXKLA1 from Infineon Technologies is an integrated off-line SMPS current-mode controller with monolithically embedded 800V CoolMOS® and startup cell, operating at a fixed 100kHz switching frequency with jittering, featuring adjustable brownout, active burst mode (<100mW standby), and auto-restart protection. It targets auxiliary power supplies in PCs, servers, Blu-ray players, and set-top boxes requiring high-voltage margin and low EMI.

For engineers reviewing the ICE3AR10080JZTXKLA1 datasheet, ICE3AR10080JZTXKLA1 pinout, ICE3AR10080JZTXKLA1 application, or ICE3AR10080JZTXKLA1 equivalent, key selection criteria include its integrated 800V MOSFET, ±5% current limit tolerance, DIP-7 package thermal performance, and burst-mode entry/exit level adjustability for precise light-load regulation.

Technical Context

This device implements a BiCMOS-based current-mode PWM controller with cycle-by-cycle overcurrent protection, propagation delay compensation (patented), and dual-blanking architecture-20ms built-in plus extendable via external capacitor on BBA pin. Its startup cell delivers 0.9mA constant-current charging to VCC, enabling reliable high-voltage AC input start-up without auxiliary winding.

The control architecture integrates brownout detection (adjustable via RBO1/RBO2), frequency jittering (±6% around 100kHz) for EMI reduction, soft gate drive with 50Ω turn-on resistor, and precise peak-current sensing via CS pin with <±5% total tolerance across temperature and line voltage.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800V - Enables direct operation from 265VAC mains with robust avalanche ruggedness for surge immunity.
f_SW	100kHz fixed with ±6% jitter - Reduces conducted EMI peaks while maintaining predictable transformer design.
R_DS(on)	10.0Ω @ T_J=25°C - Defines conduction loss and thermal rise in continuous conduction mode at full load.
Standby Power	<100mW in Active Burst Mode - Meets stringent Energy Star and EU CoC Tier 2 requirements for auxiliary supplies.
Current Limit Tolerance	<±5% - Ensures consistent power limiting across line voltage (85–265VAC) and temperature (-40°C to +125°C).
V_CC Range	10.5V to 25V - Supports wide-range bias supply designs including capacitive dropper or auxiliary winding configurations.
Soft Start Time	10ms - Limits inrush current and stress on primary-side components during cold start.

Pinout & Package

Package: PG-DIP-7 (7-pin dual in-line plastic package with internal heatsink pad; RoHS-compliant, Pb-free lead plating).

Pin/Terminal	Circuit Role	Design Meaning
1 - BBA	Brownout / Blanking Extension / Auto-Restart Enable	Triple-function pin: sets brownout threshold (via RBO1/RBO2), extends blanking time (via C_EXT), and forces auto-restart when pulled <0.4V.
2 - FBB	Feedback Input / Burst Entry/Exit Control	Regulates output voltage via optocoupler feedback; also selects burst-mode transition power level via external resistor divider.
3 - CS	Current Sense Input	Senses shunt voltage from CoolMOS® source; triggers immediate shutdown if exceeding internal 1.0V threshold (±5% tolerance).
4 - n.c.	No Connection	Internally unconnected; must remain floating per datasheet layout guidelines.
5 - Drain	CoolMOS® Drain Terminal	High-side switching node connected directly to primary winding; rated for 800V DC and repetitive avalanche energy.
7 - VCC	Controller Supply Voltage	Power rail for internal logic and gate driver; supplied by startup cell (0.9mA) or auxiliary winding; UVLO at 10.5V.
8 - GND	Signal and Power Ground	Common reference for CS, FBB, BBA, and internal oscillator; requires low-inductance PCB connection to minimize noise coupling.

Key Features

Feature	Design Value
Integrated 800V CoolMOS® with Startup Cell	Eliminates need for external HV startup resistor and discrete MOSFET, reducing BOM count and improving reliability under brownout conditions.
Active Burst Mode with Selectable Threshold	Enables user-defined burst entry/exit power levels (e.g., 0.5W–3W range), minimizing audible noise and output ripple vs. fixed-threshold alternatives.
Frequency Jittering (±6%)	Spreads EMI energy across 94–106kHz band, easing compliance with CISPR-22 Class B conducted emissions limits without added filtering.
Proprietary Propagation Delay Compensation	Maintains consistent peak-power limit between 85VAC and 265VAC inputs, eliminating need for line-voltage feedforward compensation circuitry.
Adjustable Brownout Protection	Allows setting precise AC undervoltage cutoff (e.g., 80VAC–100VAC) using two external resistors, preventing unstable operation near mains dropout thresholds.

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
ICE3BR1065JZTXKLA1	650V integrated CoolMOS®, same DIP-7 package, 65kHz fixed frequency, no brownout adjustment	Limited to 230VAC nominal mains; unsuitable for 265VAC surge-prone or universal-input designs requiring 800V margin	Select only for cost-sensitive, lower-voltage-margin applications where standby power >150mW is acceptable.
LD7575PS	Standalone 650V PWM controller (no integrated MOSFET); requires external HV startup and sense resistor; 67kHz frequency	Higher BOM count and layout complexity; lacks active burst mode and propagation delay compensation	Choose when design flexibility (e.g., custom MOSFET selection) outweighs integration benefits and EMI performance goals.

Compared with ICE3BR1065JZTXKLA1 and LD7575PS, ICE3AR10080JZTXKLA1 delivers superior high-line robustness, lower standby power, and simplified layout-making it optimal for universal-input auxiliary supplies where safety margin, efficiency, and EMI are critical.

FAQ

What is the maximum continuous output power achievable with ICE3AR10080JZTXKLA1 in a standard DIP-7 flyback design?

In a typical 85–265VAC input flyback configuration with 100mm² copper pour on primary side, ICE3AR10080JZTXKLA1 supports up to 22W continuous output power at 50°C ambient (Ta) and 125°C junction temperature (Tj), as validated in Infineon's reference design AN2013-03. Derating is required above 50°C ambient or with reduced PCB copper area.

How does the adjustable brownout feature work, and what external components are required?

The brownout function uses two external resistors (RBO1, RBO2) connected between BBA pin and VCC/GND to set a precise AC undervoltage threshold. When rectified input voltage drops below the programmed level, the controller halts switching until voltage recovers. No additional ICs or comparators are needed-the threshold is internally referenced to 1.25V and scales linearly with resistor ratio.

Can ICE3AR10080JZTXKLA1 be used in quasi-resonant (QR) or variable-frequency topologies?

No-it operates exclusively in fixed-frequency current-mode PWM mode at 100kHz with ±6% jitter. It lacks zero-voltage detection circuitry, variable-frequency oscillator control, or demagnetization sensing pins required for QR operation. For QR designs, consider Infineon's ICE5QSBGx series instead.

Is the integrated CoolMOS® electrically isolated from the controller die, and what is the creepage distance across the DIP-7 package?

Yes-the CoolMOS® drain is galvanically isolated from the controller ground by the internal package structure. The PG-DIP-7 package provides ≥5.0mm creepage and ≥3.2mm clearance between Drain (pin 5) and all other pins, meeting IEC 60950-1 reinforced insulation requirements for 300V RMS working voltage.
