Product details

Overview

ICE3AR2280JZXKLA1 from Infineon Technologies is an integrated off-line SMPS current-mode controller with monolithically embedded 800V avalanche-rugged CoolMOS® and startup cell in PG-DIP-7 package. It delivers 43W at 230VAC ±15%, operates at fixed 100kHz switching frequency with jitter, features active burst mode for <100mW standby power, and includes adjustable brownout, auto-restart protection, and propagation delay compensation - targeting auxiliary power supplies for PCs and servers.

For engineers reviewing the ICE3AR2280JZXKLA1 datasheet, ICE3AR2280JZXKLA1 pinout, ICE3AR2280JZXKLA1 application, or ICE3AR2280JZXKLA1 equivalent, key selection considerations include its integrated 800V MOSFET voltage margin, selectable burst entry/exit thresholds, ±5% current limit tolerance, 50°C hysteresis overtemperature protection, and DIP-7 thermal performance without external heatsink at Ta=50°C.

Technical Context

This device implements a current-mode PWM controller with BiCMOS process technology enabling 10.5–25V VCC operation and low quiescent consumption. Its control architecture integrates cycle-by-cycle peak current limiting with leading-edge blanking (20ms base + extendable via BBA capacitor) and patented propagation delay compensation for consistent power limiting across input line variations.

The integrated 800V CoolMOS® features soft gate drive with built-in 50Ω turn-on resistor and avalanche ruggedness, while the startup cell delivers 0.9mA constant-current charging to CVCC until VCC reaches 17V, after which it disconnects to eliminate standby loss. Brownout detection, frequency jittering, and active burst mode are implemented in analog hardware without microcontroller intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800V - Enables reliable operation under 380VDC rectified mains transients without derating.
f_SW	100kHz fixed with jitter - Reduces EMI peak amplitude by spreading energy across 100–105kHz band.
R_DS(on)	2.26Ω typ @ 25°C - Sets conduction loss and thermal rise in 43W AC/DC adapter designs.
Standby Power	<100mW - Achieved via Active Burst Mode with selectable entry/exit thresholds and 0.3V feedback swing.
Current Limit Tolerance	±5% - Ensures accurate, repeatable overcurrent protection across temperature and production lots.
Soft Start Time	10ms - Limits inrush stress on transformer, rectifier, and bulk capacitor during cold start.
OTP Hysteresis	50°C - Prevents thermal oscillation during overload recovery; trips at 150°C, resets at 100°C.

Pinout & Package

Package: PG-DIP-7 (Plastic Dual In-line Package, 7-pin, 0.3" wide, 2.54mm pitch), RoHS-compliant, Pb-free lead plating. Designed for through-hole mounting with creepage/clearance compliance for reinforced insulation in 230VAC applications.

Pin/Terminal	Circuit Role	Design Meaning
1 - BBA	Brownout / Blanking Extension / Auto-Restart Enable	Combines three functions: brownout shutdown below adjustable threshold, external capacitor-controlled blanking extension for overload, and logic-low (<0.4V) forced auto-restart trigger.
2 - FBB	Feedback Input / Burst Mode Control	Regulates output voltage via optocoupler feedback; also sets burst entry/exit power level via external resistor divider.
3 - CS	Current Sense Input	Monitors source voltage of integrated CoolMOS®; triggers immediate gate shutdown when sensed voltage exceeds internal current limit comparator threshold.
4 - n.c.	No Connection	Internally unconnected; must remain floating - no routing or soldering permitted.
5 - Drain	CoolMOS® Drain Terminal	High-side switching node connected directly to primary winding of flyback transformer; rated for 800V blocking.
7 - VCC	Controller Supply Voltage	Accepts 10.5–25V DC; powers internal circuitry after startup cell charges CVCC capacitor to 17V.
8 - GND	Power Ground Reference	Common return path for controller logic, gate driver, and current sense amplifier; separate from power ground in layout-critical designs.

Key Features

Feature	Design Value
Integrated 800V CoolMOS® with Startup Cell	Eliminates external high-voltage startup resistor network, reducing component count and improving reliability in universal-input adapters.
Active Burst Mode with Selectable Thresholds	Enables optimization of light-load efficiency and output ripple trade-offs via external resistors on FBB pin - not fixed internally.
Propagation Delay Compensation (Patented)	Maintains consistent peak power limit between 85VAC and 265VAC inputs by dynamically adjusting current sense timing.
Adjustable Brownout Function	Prevents unstable regulation or audible noise during brownout events by disabling switching before V_IN drops below user-defined threshold.
Soft Gate Drive with 50Ω Turn-On Resistor	Reduces EMI and dv/dt-induced false triggering by controlling MOSFET turn-on slew rate without external components.

Applications

PC Auxiliary Power Supply

DVD/Blu-ray Player SMPS

Use Scenario: Provides +5VSB and +12V standby rails for motherboard wake-on-LAN, USB charging, and system management in ATX PSUs.

IC Role / Device Role / Timing Role: Primary-side controller in flyback topology; regulates output via optocoupler feedback while maintaining <100mW no-load consumption.

Use Value: 800V MOSFET withstands 380VDC surge without snubber redesign; active burst mode meets Energy Star 6.1 standby requirements.

Use Scenario: Powers optical drive motor, laser diode bias, and digital logic in consumer disc players operating from universal AC input.

IC Role / Device Role / Timing Role: Integrated controller-MOSFET eliminates discrete gate driver and HV startup components; 100kHz jitter reduces conducted EMI in compact enclosures.

Use Value: Adjustable brownout prevents dropout during line sags; ±5% current limit ensures consistent overcurrent trip across temperature and unit-to-unit variation.

Set-Top Box Power Supply

Server Standby Converter

Use Scenario: Delivers isolated 3.3V/5V/12V rails for SoC, memory, and HDMI interface in cable/satellite receivers with tight EMI limits.

Equivalent & Alternatives

The following parts are listed as comparable options for similar integrated SMPS controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE3BR2280JZ	650V integrated CoolMOS®, same DIP-7 package and pinout, lacks brownout adjustment and burst-level selectability.	Suitable only for 115VAC-only or low-surge environments; requires external brownout circuitry for universal input.	Select when cost sensitivity outweighs 800V margin need and design uses fixed 115VAC input.
LD7575P	Standalone 650V PWM controller (no integrated MOSFET); requires external HV startup, gate driver, and sense resistor.	Higher BOM count and layout complexity; enables custom MOSFET selection but increases design validation effort.	Select when flexibility in MOSFET R_DS(on), voltage rating, or topology (e.g., forward) is required.

Compared with ICE3BR2280JZ and LD7575P, ICE3AR2280JZXKLA1 provides higher voltage safety margin, lower component count, and tighter light-load regulation - making it optimal for universal-input, space-constrained, and EMI-sensitive auxiliary supplies where integration and reliability are prioritized over MOSFET customization.

FAQ

What is the maximum continuous output power supported by ICE3AR2280JZXKLA1?

The ICE3AR2280JZXKLA1 supports up to 43W at 230VAC ±15% and 28W at 85–265VAC universal input, measured at Ta=50°C with no copper heatsink area. This rating assumes proper PCB layout per Infineon's recommended thermal pad and trace guidelines in the datasheet Figure 32.

How does the BBA pin function in brownout mode versus auto-restart enable?

In brownout mode, the BBA pin monitors input-derived voltage via external resistor divider to disable switching when AC line drops below a user-set threshold. As auto-restart enable, pulling BBA below 0.4V forces immediate gate shutdown and initiates auto-restart cycle - independent of brownout or overload conditions.

Can the switching frequency be adjusted externally?

No - the ICE3AR2280JZXKLA1 uses an internal oscillator fixed at 100kHz with ±5% jitter applied to reduce EMI peaks. There is no external frequency programming pin or resistor option; frequency is not user-adjustable.

Is the integrated CoolMOS® rated for repetitive avalanche energy?

Yes - the integrated 800V CoolMOS® is specified for repetitive avalanche operation per Infineon's datasheet Section 5, with E_AS = 120mJ at T_j=25°C. This enables robust handling of transformer leakage inductance spikes without external clamping in properly designed flyback circuits.
