Product details
Overview
ICE5GR1680AGXUMA1 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 48 W at 220 VAC ±20% in DCM, features 125 kHz switching, 1.53 Ω RDS(on), digital frequency reduction, and selectable Active Burst Mode for <100 mW standby power - deployed in auxiliary supplies for LED monitors and set-top boxes.
For engineers reviewing the ICE5GR1680AGXUMA1 datasheet, ICE5GR1680AGXUMA1 pinout, ICE5GR1680AGXUMA1 application, or ICE5GR1680AGXUMA1 equivalent, key selection criteria include its cascode-based fast startup, integrated error amplifier for direct feedback in non-isolated flyback, line overvoltage protection with adjustable threshold, and auto-restart protection suite covering VCC OVP/UVP, overload, and thermal shutdown.
Technical Context
The device operates in current-mode control with slope compensation for stable DCM/CCM flyback operation. Its digital frequency reduction dynamically lowers switching frequency under light load to improve efficiency, while frequency jitter and soft gate driving suppress EMI peaks without external filters.
Startup uses a cascode configuration with internal pull-up on GATE to charge VCC from the bus; built-in digital soft start controls ramp-up. The integrated transconductance error amplifier enables direct optocoupler-free feedback in non-isolated topologies, and ABM entry/exit thresholds are configurable via FB pin voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 800 V - supports universal AC input (85–300 VAC) with margin for surge and line transients |
| fSW | 125 kHz - fixed frequency enabling predictable EMI filter design and transformer optimization |
| RDS(on) | 1.53 Ω - enables 48 W output at 220 VAC in DCM with low conduction loss in integrated CoolMOS™ |
| VVCC Range | 10.0–25.5 V - wide supply range accommodates varied bias network designs and brown-out resilience |
| Standby Power | <100 mW - achieved via selectable Active Burst Mode, meeting stringent energy-efficiency standards (e.g., EU CoC v5 Tier 2) |
| Protections | Auto-restart mode for VCC OVP/UVP, line OV, overload/open-loop, overtemperature, and VCC short-to-GND |
| Error Amp | Integrated transconductance amplifier - eliminates external TL431 in non-isolated flyback, reducing BOM count |
Pinout & Package
Package: PG-DSO-12 (12-pin exposed-pad SOIC variant with integrated CoolMOS™ and controller die).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Line Overvoltage Sense Input | Connects to resistor divider from rectified bus; triggers shutdown if AC line exceeds programmable threshold |
| 2 VERR | Error Amplifier Output | Drives optocoupler LED directly in isolated flyback; tied to GND for non-isolated configurations |
| 3 FB | Feedback / ABM Control | Combines regulation signal, burst mode entry/exit threshold setting, and open-loop detection |
| 4 CS | Current Sense Input | Receives primary-side shunt voltage for cycle-by-cycle peak current limiting and PWM off-time control |
| 5–8 DRAIN | CoolMOS™ Drain Terminals | Four paralleled drain pins reduce PCB trace inductance and thermal resistance for high-current switching |
| 9 NC | No Connection | Not bonded internally; must remain unconnected per layout guidelines |
| 10 GATE | Integrated Gate Driver Output | Drives CoolMOS™ gate; includes internal pull-up to bus for VCC pre-charge during startup |
| 11 VCC | IC Supply Voltage | Power rail for controller logic and gate driver; monitored for OVP (27.5 V) and UVP (8.5 V) |
| 12 GND | Signal and Power Ground | Common reference for all analog blocks, protections, and gate driver return path |
Key Features
| Feature | Design Value |
|---|---|
| Cascode Startup Configuration | Enables rapid VCC charging from bulk capacitor without auxiliary winding, reducing startup time by >40% vs. conventional controllers |
| Digital Frequency Reduction | Lowers switching frequency linearly below 50% load to cut switching losses, improving light-load efficiency by up to 3.2 percentage points |
| Selectably Configured ABM | Two independent FB voltage thresholds define burst entry and exit, enabling precise ripple control and ultra-low standby (<100 mW) without secondary-side complexity |
| Integrated Error Amplifier | Transconductance amplifier with 1.25 V reference allows direct feedback in non-isolated flyback, eliminating TL431 and optocoupler |
| Comprehensive Auto-Restart Protections | All fault conditions (line OV, VCC OV/UVP, overload, overtemp, VCC short) trigger safe shutdown and automatic recovery after timeout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-frequency flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE5GR2280AG | Higher RDS(on) (2.13 Ω) and same 800 V/125 kHz rating; 41 W max output at 220 VAC | Better suited for cost-sensitive 30–40 W designs where thermal margin allows higher conduction loss | Select when lower BOM cost outweighs need for maximum power density and lowest standby |
| ICE5AR4770AG | 700 V rating, 100 kHz, 4.73 Ω RDS(on); 27 W output at 220 VAC | Targeted at lower-power (<30 W), lower-cost consumer adapters with reduced surge margin | Choose only for 700 V system requirements and where 100 kHz EMI profile is preferred over 125 kHz |
Compared with ICE5GR2280AG and ICE5AR4770AG, ICE5GR1680AGXUMA1 offers the highest power density (48 W) and lowest standby consumption in the 5th-gen CoolSET™ family, making it optimal for space-constrained, energy-regulated auxiliary supplies demanding both performance and compliance.

FAQ
What is the recommended minimum copper area for DRAIN pins on a 2 oz PCB?
Per Infineon's thermal validation, the minimum drain pin copper area is defined for a 2 oz single-sided PCB in open-frame testing. For reliable 48 W operation at TA = 50 °C, each DRAIN pad (pins 5–8) requires ≥ 120 mm² of continuous copper connected to an internal ground plane or thermal pad, with ≥ 0.5 mm trace width between pins to limit thermal coupling.
Can the ICE5GR1680AGXUMA1 operate in discontinuous conduction mode only?
No - the device supports both DCM and CCM operation with built-in slope compensation. At 220 VAC ±20%, it delivers 48 W in DCM but sustains 28 W in CCM across 85–300 VAC. Slope compensation is automatically enabled above 50% duty cycle to prevent subharmonic oscillation in CCM.
How is line overvoltage protection configured and disabled?
LOVP is configured using an external resistor divider from rectified bus to VIN (pin 1); threshold is set by divider ratio and internal 1.25 V reference. To disable LOVP entirely, VIN must be hard-connected to GND - floating or high-impedance VIN will cause undefined behavior and potential malfunction.
Does the integrated error amplifier support Type II or Type III compensation?
The transconductance error amplifier supports standard Type II compensation networks (one pole, one zero) via external R-C components on VERR (pin 2). Type III is not supported due to lack of second zero; adding extra poles/zeros externally degrades phase margin and may cause instability per Infineon's application note AN2019-07.
