Product details

Overview

ICE5AR2280CZXKLA1 from Infineon Technologies is a fixed-frequency 800 V integrated power IC (CoolSET™) combining a PWM controller and avalanche-rugged CoolMOS™ in a single PG-DIP-7 package, operating at 100 kHz with 2.13 Ω R_DS(on), supporting up to 40 W output in flyback and 700 mA in non-isolated buck topologies for auxiliary power supplies in home appliances and smart metering.

For engineers reviewing the ICE5AR2280CZXKLA1 datasheet, ICE5AR2280CZXKLA1 pinout, ICE5AR2280CZXKLA1 application, or ICE5AR2280CZXKLA1 equivalent, key selection criteria include its 100 kHz switching frequency, integrated error amplifier for direct feedback in non-isolated designs, selectable Active Burst Mode, line overvoltage protection (CZ version), and cascode-based fast startup capability.

Technical Context

The ICE5AR2280CZXKLA1 implements peak current mode control with digital slope compensation, cycle-by-cycle current limiting, and built-in soft-start timing. Its cascode configuration enables rapid VCC precharging and startup within 10 ms, while digital frequency reduction and jittered oscillator operation reduce EMI across light-load to 50% load conditions.

This fifth-generation CoolSET™ supports both isolated flyback (via optocoupler + TL431) and non-isolated buck/flyback topologies using its integrated transconductance error amplifier (VERR pin disabled; VIN pin used for line overvoltage detection). Protection functions include auto-restart-mode line overvoltage (LOVP), VCC OVP/UVP, overload, open-loop, and overtemperature detection with thermal hysteresis.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - Enables direct rectified AC input handling up to 300 VAC without external HV MOSFET.
Switching Frequency	100 kHz - Higher than 65 kHz variants, enabling smaller magnetics and improved power density in flyback designs.
R_DS(on)	2.13 Ω - Confirmed typical value at T_j = 25°C; determines conduction loss and max continuous output power (24 W CCM @ 85–300 VAC).
VCC Operating Range	10.0 V to 25.5 V - Supports wide-range auxiliary supply design with low quiescent current during standby.
Active Burst Mode	Selectably enabled - Reduces standby power via configurable entry/exit thresholds and controlled output ripple (< ±5% VO).
Line Overvoltage Protection	Integrated on VIN pin (CZ version) - Triggers auto-restart shutdown above programmable AC line threshold (e.g., >280 VAC).
Error Amplifier	Integrated transconductance type - Eliminates external op-amp in non-isolated buck/flyback, enabling direct feedback to FB pin.

Pinout & Package

ICE5AR2280CZXKLA1 is housed in a Pb-free, halogen-free PG-DIP-7 package (7-pin dual in-line plastic) with creepage ≥5.0 mm and isolation rating suitable for industrial applications per JEDEC qualification.

Pin/Terminal	Circuit Role	Design Meaning
1	VIN	Input line overvoltage sense - Connected to rectified bus via resistor divider; enables programmable LOVP shutdown.
2	GND	Power and signal reference ground - Shared return for controller logic, gate driver, and protections.
3	FB	Feedback input - Receives voltage-scaled output signal for regulation; interfaces directly with internal error amplifier in non-isolated mode.
4	CS	Current sense - Monitors primary-side current via sense resistor; triggers cycle-by-cycle limiting and slope compensation.
5	VCC	IC supply rail - Powers internal circuitry; internally regulated; features undervoltage lockout (10.0 V) and overvoltage shutdown (25.5 V).
6	GATE	High-side gate driver output - Drives CoolMOS™ source-follower stage; designed for cascode configuration with low propagation delay.
7	DRAIN	High-voltage drain terminal - Connects to CoolMOS™ drain; rated for 800 V blocking; carries full primary current in flyback/buck.

Key Features

Feature	Design Value
Digital frequency reduction	Reduces switching frequency under light load to improve efficiency without audible noise or regulation instability.
Fast startup via cascode	Achieves <10 ms VCC ramp-up using internal high-side bootstrap path, eliminating external startup resistor.
Integrated error amplifier	Enables direct feedback in non-isolated buck/flyback without TL431 or optocoupler, reducing BOM count and layout area.
Comprehensive auto-restart protections	Covers line overvoltage, VCC OVP/UVP, overload, open-loop, overtemperature, and VCC short-to-GND - all recover automatically after fault removal.
EMI-optimized gate drive	Soft gate driving and frequency jitter suppress peak spectral energy, easing compliance with CISPR-22 Class B limits.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-frequency offline SMPS controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE5BR2280BZ	65 kHz switching frequency, same 800 V/2.13 Ω CoolMOS™, no VIN/LOVP pin (BZ version)	Lacks line overvoltage protection; requires external circuitry for brownout/overvoltage response	Preferred where lower EMI priority exists and LOVP is managed externally or unnecessary
ICE5AR3995CZ	950 V CoolMOS™, same 100 kHz, higher R_DS(on) (3.46 Ω), identical CZ pinout and protections	Better suited for universal-input 230 VAC-only or surge-prone environments requiring higher V_DS margin	Select when input surges exceed 800 V or design targets >265 VAC nominal operation

Compared with ICE5BR2280BZ, ICE5AR2280CZXKLA1 offers higher frequency and integrated LOVP but trades off slightly higher conduction loss at full load; versus ICE5AR3995CZ, it delivers lower R_DS(on) and better efficiency at 115 VAC input, making it optimal for cost-sensitive 100–240 VAC auxiliary supplies.

FAQ

What is the purpose of the VIN pin on ICE5AR2280CZXKLA1?

The VIN pin serves as the input for line overvoltage protection (LOVP) in the CZ version. It connects to the rectified AC bus via a resistor divider; when the sensed voltage exceeds the internal threshold (~2.5 V), the IC initiates auto-restart shutdown to protect downstream circuitry from overvoltage events. This function is absent in BZ variants.

Can ICE5AR2280CZXKLA1 be used in non-isolated buck topology without external op-amps?

Yes - the device integrates a transconductance error amplifier referenced to GND. In buck configurations, the FB pin accepts direct feedback from the output divider, eliminating the need for TL431 or external op-amps. The VERR pin is unused (tied to GND), and regulation accuracy is ±2% over temperature and line.

How does Active Burst Mode operate in ICE5AR2280CZXKLA1?

Active Burst Mode (ABM) reduces switching activity during light loads by pausing PWM bursts until output voltage droop crosses a user-selectable threshold. Entry/exit levels are set via external resistors on the FB pin, enabling precise control of standby power (<100 mW) and output ripple (<±5%), with automatic recovery upon load increase.

What thermal derating applies to ICE5AR2280CZXKLA1 in open-frame designs?

In an open-frame design on 2 oz copper with minimum drain pad area, the device delivers 24 W in CCM at 85–300 VAC with T_j = 125°C and T_a = 50°C. Derating follows a linear 0.33 W/°C slope above 50°C ambient; full-rated output requires ≥100 mm² copper pour on the DRAIN pin for effective heat spreading.
