Product details
Overview
ICE5GSAGXUMA1 from Infineon is a fixed-frequency current-mode PWM controller in PG-DSO-8 package, designed for off-line flyback converters in cascode configuration. It operates at 125 kHz, supports DCM/CCM with slope compensation, delivers up to 66 W at 85–300 VAC in CCM, and achieves <100 mW standby power via selectable Active Burst Mode. Used in auxiliary power supplies for TVs, monitors, and home appliances.
For engineers reviewing the ICE5GSAGXUMA1 datasheet, ICE5GSAGXUMA1 pinout, ICE5GSAGXUMA1 application, or ICE5GSAGXUMA1 equivalent, key selection criteria include its 125 kHz switching frequency, integrated error amplifier for direct feedback in non-isolated flyback, digital frequency reduction for light-load efficiency, soft gate driving for EMI suppression, and comprehensive auto-restart protections including LOVP, VCC OVP/UVP, and CS short-to-GND.
Technical Context
The ICE5GSAGXUMA1 implements peak current mode control with built-in slope compensation for stable DCM/CCM operation across input ranges (85–300 VAC). Its digital frequency reduction dynamically lowers switching frequency below 50% load, improving efficiency without compromising regulation.
It integrates a transconductance error amplifier (VERR) enabling direct optocoupler-free feedback in non-isolated flyback topologies, and features a cascode-configured startup path with controlled VCC pre-charging for fast turn-on. All protection functions-including line overvoltage, VCC OVP/UVP, overload/open-loop, overtemperature, and CS short-to-GND-operate in auto-restart mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 125 kHz - fixed frequency enables predictable EMI filtering and transformer design. |
| Operating VCC Range | 10.0–25.5 V - wide supply range supports robust startup and brown-out immunity. |
| Standby Power | <100 mW - achieved via selectable Active Burst Mode with controllable output ripple. |
| Output Power (CCM) | 66 W at 85–300 VAC - validated maximum for open-frame design at 50 °C ambient, 125 °C junction. |
| Protection Modes | Auto-restart for LOVP, VCC OVP/UVP, overload/open-loop, overtemperature, CS short-to-GND - ensures fail-safe recovery without latch-off. |
| Error Amplifier | Integrated transconductance amplifier - eliminates external TL431 in non-isolated flyback, reducing BOM count. |
| Startup Configuration | Cascode-based VCC pre-charge - enables fast startup without auxiliary winding or dedicated startup circuitry. |
Pinout & Package
Package: PG-DSO-8 (8-pin, exposed pad, RoHS-compliant, halogen-free mold compound).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Line Over Voltage Protection input | Senses rectified AC bus via resistor divider; disabling LOVP requires grounding this pin. |
| 2 VERR | Error amplifier output | Direct feedback node for non-isolated flyback; must be grounded for isolated configurations. |
| 3 FB | Feedback & ABM control | Combines regulation signal, burst entry/exit threshold setting, and overload detection. |
| 4 CS | Current sense input | Connects to primary-side shunt; triggers cycle-by-cycle current limit and detects CS-to-GND short. |
| 5 SOURCE | Low-side MOSFET source | Reference node for internal low-side switch and VCC diode; connects to external MOSFET source. |
| 6 GATE | Gate driver output | Drives external power MOSFET gate; includes internal pull-up for VCC capacitor charging during startup. |
| 7 VCC | Positive supply rail | IC power input (10.0–25.5 V); protected by OVP (27.5 V typ.) and UVP (8.5 V typ.). |
| 8 GND | Power and signal ground | Common reference for all analog and power sections; ties to PCB thermal pad for thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced Active Burst Mode | Selectably configured entry/exit thresholds enable ultra-low standby power (<100 mW) with minimal output voltage ripple. |
| Digital Frequency Reduction | Automatically lowers switching frequency under light load to reduce switching losses while maintaining regulation. |
| Integrated Error Amplifier | Transconductance amplifier supports direct feedback in non-isolated flyback, eliminating TL431 and optocoupler. |
| Soft Gate Driving & Frequency Jitter | Reduces EMI peaks by spreading spectral energy and smoothing MOSFET turn-on/turn-off transitions. |
| Comprehensive Auto-Restart Protections | Seven fault conditions (LOVP, VCC OVP/UVP, overload, overtemp, CS short, VCC short) all recover automatically after fault clears. |

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 |
|---|---|---|---|
| ICE5ASAGXUMA1 | 100 kHz switching frequency; lower max output power (60 W CCM at 85–300 VAC); identical pinout and protection set. | Better suited for cost-sensitive, lower-power auxiliary supplies where EMI filtering simplicity outweighs peak efficiency. | Choose when 100 kHz simplifies EMI filter design and 60 W output suffices. |
| ICE5QSAGXUMA1 | Quasi-resonant (QR) mode support; variable frequency operation; higher peak efficiency at light loads but increased complexity. | Targeted at high-efficiency primary-side regulated adapters where QR reduces switching loss beyond what frequency reduction achieves. | Choose only if QR topology is already implemented and system-level efficiency gain justifies added design effort. |
Compared with ICE5ASAGXUMA1, ICE5GSAGXUMA1 delivers higher power density and light-load efficiency via 125 kHz operation and enhanced ABM; versus ICE5QSAGXUMA1, it trades QR flexibility for simpler fixed-frequency control, lower BOM cost, and guaranteed EMI predictability.

FAQ
What is the purpose of the VERR pin?
The VERR pin is the output of the integrated transconductance error amplifier. In non-isolated flyback designs, it connects directly to the primary-side feedback network to regulate output voltage without an optocoupler or TL431. For isolated configurations, VERR must be tied to GND to disable the internal amplifier and allow external feedback via the FB pin.
How does Active Burst Mode reduce standby power?
Active Burst Mode (ABM) reduces standby power by selectively pausing switching cycles based on load demand. ICE5GSAGXUMA1 allows independent configuration of entry and exit power thresholds via external resistors on the FB pin, enabling precise control of burst depth and output voltage ripple-achieving <100 mW no-load consumption while maintaining tight regulation.
Can ICE5GSAGXUMA1 operate in continuous conduction mode?
Yes, ICE5GSAGXUMA1 supports both discontinuous (DCM) and continuous conduction mode (CCM) operation. Internal slope compensation ensures stable current-mode control across both modes. At 85–300 VAC input, it delivers up to 66 W in CCM, validated per Infineon's open-frame reference design at 50 °C ambient and 125 °C junction temperature.
What protections are included and how do they behave?
ICE5GSAGXUMA1 includes line overvoltage (LOVP), VCC over/under-voltage, overload/open-loop, overtemperature, CS short-to-GND, and VCC short-to-GND protection. All trigger auto-restart behavior: the controller halts switching, waits a fixed timeout (~1 s), then attempts normal restart. No latching or manual reset is required, ensuring autonomous recovery after transient faults.
