Product details

Overview

ICE3AR2280CJZXKLA1 from Infineon Technologies is an off-line SMPS current-mode PWM controller with integrated 800V avalanche-rugged CoolMOS® and startup cell in PG-DIP-7 package, operating at fixed 100kHz switching frequency with jittering, delivering up to 43W input power at 230VAC ±15%, and featuring active burst mode for <100mW standby power in auxiliary power supplies for PCs and servers.

For engineers reviewing the ICE3AR2280CJZXKLA1 datasheet, ICE3AR2280CJZXKLA1 pinout, ICE3AR2280CJZXKLA1 application, or ICE3AR2280CJZXKLA1 equivalent, key selection criteria include integrated 800V MOSFET voltage margin, brownout detection threshold (1V), slope compensation for CCM operation, selectable burst entry/exit level via FBB pin, and built-in auto-restart protection against overtemperature (50°C hysteresis), overload, and VCC OVP/UVP.

Technical Context

This IC implements a BiCMOS-based current-mode control architecture with cycle-by-cycle peak current limiting, 40ms leading-edge blanking, and propagation delay compensation across load conditions. Its integrated 800V CoolMOS® enables high-voltage-margin flyback designs without external HV startup circuitry.

The controller supports both discontinuous conduction mode (DCM) and continuous conduction mode (CCM) via programmable slope compensation, and features dual-function pins: BRL handles brownout detection (1V threshold), fast AC reset (0.4V–1V rising edge <1.33V/ms), and external latch enable (<0.4V), while FBB provides feedback regulation and burst mode level selection.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800V - Enables safe operation with 265VAC mains input plus line surges without external snubber stress.
f_SW	100kHz fixed with jittering - Reduces EMI peak emissions while maintaining predictable transformer design.
R_DS(on)	2.26Ω @ 25°C - Sets conduction loss budget for 43W max input power at 230VAC with thermal derating.
Standby Power	<100mW in Active Burst Mode - Meets Energy Star and EU CoC Tier 2 requirements for auxiliary supplies.
Brownout Threshold	1.0V on BRL pin - Disables switching during brownout events below nominal AC input, preventing unstable regulation.
Soft Start Time	10ms built-in - Limits inrush current and stress on primary-side components during cold start.
OTP Hysteresis	50°C - Ensures stable thermal shutdown/recovery cycling without oscillation under sustained overload.

Pinout & Package

ICE3AR2280CJZXKLA1 is housed in PG-DIP-7 package (7-pin plastic dual in-line, 10.16mm body width, 7.62mm lead pitch), with Pin 6 omitted (no connection). The package supports through-hole mounting and meets RoHS-compliant Pb-free lead plating requirements.

Pin/Terminal	Circuit Role	Design Meaning
1 - BRL	Brownout / Fast AC Reset / Latch Enable	Triple-function pin: brownout disable at ≤1.0V; fast AC reset triggered by 0.4V→1V rise <1.33V/ms; latch forced by <0.4V.
2 - FBB	Feedback Input / Burst Entry/Exit Control	Regulates output via optocoupler feedback; sets burst mode activation/deactivation thresholds via external resistor divider.
3 - CS	Current Sense Input	Monitors shunt voltage across CoolMOS® source to enforce cycle-by-cycle peak current limit and enable current-mode control.
4 - n.c.	No Connection	Internally unconnected; must remain floating per datasheet layout guidelines.
5 - Drain	CoolMOS® Drain Terminal	Primary-side high-voltage node connected directly to transformer primary winding and snubber network.
7 - VCC	Controller Supply Voltage	Power rail for internal logic and gate driver; operates 10.5–24.7V; charged via integrated startup cell from Drain.
8 - GND	Controller Ground Reference	Analog and power ground reference for all internal circuits; requires low-inductance PCB connection to minimize noise coupling.

Key Features

Feature	Design Value
Slope Compensation	Enables stable CCM operation at duty cycles >0.5, eliminating subharmonic oscillation without external components.
Active Burst Mode	Reduces standby power to <100mW by dynamically gating switching pulses based on load demand, with user-selectable entry/exit thresholds.
Integrated Startup Cell	Provides 1.0mA constant-current charging of VCC capacitor from Drain, eliminating external HV resistor and reducing no-load losses.
Frequency Jittering	Modulates 100kHz switching frequency to spread EMI energy across spectrum, easing compliance with CISPR-22 Class B limits.
Soft Gate Drive	Includes 50Ω internal turn-on resistor to dampen MOSFET gate ringing and reduce dv/dt-induced EMI and cross-conduction risk.

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
ICE3AR1780CJZ	Same DIP-7 package and feature set, but with 1.7Ω R_DS(on) and 50W max input power rating.	Higher power capability suits 65W adapters; requires larger heatsinking and higher-current transformer design.	Select when >43W output is required and board space allows increased thermal management.
ICE3BR1765JZ	650V CoolMOS®, no brownout function, 65kHz fixed frequency, no slope compensation.	Limited to lower-input-voltage applications (≤230VAC); unsuitable for CCM operation or brownout-prone regions.	Choose only for cost-sensitive, low-power (<25W), non-brownout-critical designs where EMI is less constrained.

Compared with ICE3AR1780CJZ, ICE3AR2280CJZXKLA1 trades 7W input power headroom for tighter thermal design and lower component count; versus ICE3BR1765JZ, it adds 150V MOSFET margin, brownout protection, and CCM stability-critical for global universal-input deployments.

FAQ

What is the purpose of the BRL pin's triple functionality?

The BRL pin integrates brownout detection (disables switching below 1.0V), fast AC reset (recovers from latch mode when voltage rises 0.4V→1V at <1.33V/ms), and external latch enable (forces shutdown when pulled <0.4V). This consolidation reduces external components while enabling precise AC line monitoring and fault recovery without additional logic.

How does slope compensation improve CCM operation?

Slope compensation injects a ramp signal into the current-sense comparator to prevent subharmonic oscillation when duty cycle exceeds 50% in continuous conduction mode. For ICE3AR2280CJZXKLA1, this is implemented internally-no external components needed-ensuring stable regulation across full load range without instability or audible noise.

Can the ICE3AR2280CJZXKLA1 operate without an auxiliary winding?

Yes. Its integrated startup cell draws 1.0mA constant current from the Drain pin to charge the VCC capacitor, eliminating the need for an auxiliary winding or external HV resistor. This simplifies transformer design, improves no-load efficiency, and enhances reliability by removing a common failure point in flyback topologies.

What protection features are built into the IC?

ICE3AR2280CJZXKLA1 includes auto-restart protection for overtemperature (50°C hysteresis), overvoltage (VCC OVP), undervoltage (VCC UVP), overload, open-loop faults, and external latch enable. It also features 40ms blanking time to tolerate short-duration peak loads and built-in soft-start to limit inrush current during power-up.
