Product details

Overview

ICE5GR2280AGXUMA1 from Infineon is a fixed-frequency 800 V integrated power IC (CoolSET™) combining a PWM controller and avalanche-rugged CoolMOS™ in a single DSO-12 package. It delivers up to 41 W output at 220 V AC ±20% in DCM, operates at 125 kHz, features 2.13 Ω R_DS(on), and supports non-isolated/isolated flyback topologies for auxiliary power supplies in home appliances and monitors.

For engineers reviewing the ICE5GR2280AGXUMA1 datasheet, ICE5GR2280AGXUMA1 pinout, ICE5GR2280AGXUMA1 application, or ICE5GR2280AGXUMA1 equivalent, key selection considerations include its selectable Active Burst Mode entry/exit threshold, integrated error amplifier for direct feedback, digital frequency reduction for light-load efficiency, and comprehensive auto-restart protections including line overvoltage, VCC UV/OV, overload, and overtemperature.

Technical Context

This CoolSET™ integrates a current-mode PWM controller with an 800 V CoolMOS™ power transistor in cascode configuration, enabling fast startup via internal VCC pre-charging through the GATE pull-up resistor. Its digital control unit implements slope compensation for stable DCM/CCM operation and cycle-by-cycle current limiting with propagation delay compensation.

The device uses digital frequency reduction below 50% load and combines frequency jittering with soft gate driving to reduce EMI. The ABM mode is configurable via external resistors on FB, and the integrated transconductance error amplifier allows direct feedback in non-isolated flyback without optocoupler or TL431.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-frequency flyback controller with integrated HV MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE5GR4780AG	Higher R_DS(on) (4.13 Ω), same 800 V/125 kHz, lower output power (27.5 W @ 220 VAC)	Suitable for ≤25 W auxiliary supplies where thermal margin is constrained	Select when lower cost and reduced output power are acceptable trade-offs for simpler thermal design
ICE5AR4770AG	700 V rating, 100 kHz, 4.73 Ω R_DS(on), max 27 W output	Targeted for lower-input-voltage or cost-sensitive 700 V designs with relaxed surge requirements	Choose only if 700 V breakdown suffices and 125 kHz switching is not required for size optimization

Compared with ICE5GR4780AG and ICE5AR4770AG, ICE5GR2280AGXUMA1 provides the highest power density (41 W) in the 5th-gen CoolSET™ family due to its 2.13 Ω R_DS(on), making it optimal for space-constrained auxiliary supplies needing >35 W output without increasing switching frequency or compromising EMI.

FAQ

What is the purpose of the VIN pin on ICE5GR2280AGXUMA1?

The VIN pin serves as the input for Line Over Voltage Protection (LOVP). It connects to the rectified AC bus via an external resistor divider to monitor input voltage. When the sensed voltage exceeds the internal threshold, the IC disables switching to protect downstream components. Connecting VIN directly to GND disables this protection function entirely, as confirmed in the official Infineon datasheet section 1.1.

Can ICE5GR2280AGXUMA1 operate in non-isolated flyback topology without an optocoupler?

Yes. The device integrates a transconductance error amplifier connected to the VERR pin, enabling direct primary-side feedback regulation. In non-isolated configurations, VERR is used as the regulation node while FB handles burst mode control and overload detection-eliminating the need for TL431 and optocoupler, as verified in Figure 2 and section 3.6 of the datasheet.

How does the cascode startup configuration improve system reliability?

The cascode startup uses an internal pull-up resistor from the DRAIN node to the GATE pin, allowing the CoolMOS™ to conduct briefly during initial AC application and charge the VCC capacitor directly from the high-voltage bus. This removes dependence on external high-voltage start-up networks-reducing component count, failure points, and startup time to under 100 ms, as documented in sections 3.1 and 3.2 of the datasheet.

What protection mechanisms restart automatically after fault clearance?

All protections-including line overvoltage, VCC over/under voltage, overload/open-loop, overtemperature, and VCC short-to-GND-operate in auto-restart mode. After fault removal, the IC resumes normal operation without manual reset or external intervention, as explicitly stated in the "Features" section and section 3.7.6 ("Protection modes") of the datasheet.
