Product details
Overview
ICC80QSGXUMA1 from Infineon Technologies is a quasi-resonant flyback controller with secondary-side regulation (SSR) for battery charger applications up to 130 W, featuring valley-switching DCM/CCM-prevention operation, burst mode for <30 mW standby power, and integrated protections including primary OCP, output OVP, brownin/brownout, and OTP. It interfaces directly with CoolMOS™ P7 MOSFETs and supports adaptive brownout level triggering based on bus voltage ripple.
For engineers reviewing the ICC80QSGXUMA1 datasheet, ICC80QSGXUMA1 pinout, ICC80QSGXUMA1 application, or ICC80QSGXUMA1 equivalent, key selection criteria include SSR-based current control accuracy, adjustable on-time mapping at valley position, TD-pin configurable hysteresis, and gate driver output reduction during burst mode to minimize standby losses.
Technical Context
The ICC80QSGXUMA1 implements voltage-mode control in quasi-resonant flyback topologies, using zero-crossing detection (ZCD) and valley-switching logic to synchronize MOSFET turn-on with minimum drain voltage. Its digital state machine dynamically selects between QRM, DCM, and burst modes based on load and input conditions.
Input voltage sensing via VIN pin enables real-time bus ripple–adaptive brownout protection-raising the brownout threshold at higher power to prevent transformer saturation-and supports externally configurable hysteresis via TD-to-VIN resistor. The VS pin provides direct load-current–proportional feedback for precise battery charging current regulation without optocoupler dependency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28780 (Texas Instruments) | Active-clamp forward/flyback hybrid controller; requires external clamp FET and different ZCD interface | Targets higher-power (>150 W), active-clamp topologies; lacks SSR-based current regulation | Select when designing active-clamp flyback or needing programmable soft-start slope |
| ICE5QSAG (Infineon) | Quasi-resonant controller with primary-side regulation (PSR); no VS pin or SSR capability | Used in cost-sensitive, lower-accuracy chargers where ±5% current tolerance is acceptable | Select only if SSR-level current accuracy is not required and optocoupler elimination is sufficient |

FAQ
What is the function of the VS pin in ICC80QSGXUMA1?
The VS pin senses a load-current–proportional feedback signal from the secondary side, enabling secondary-side regulation (SSR) for precise battery charging current control without optocoupler or TL431. It operates as the primary regulation input in voltage-mode control, directly determining output current accuracy within ±3% over line, load, and temperature.
How does the TD pin configure brownin/brownout hysteresis?
A resistor between TD and VIN pins creates an offset voltage on VIN during RUN state, shifting the brownout threshold upward relative to brownin. The internal pull-up resistors (10 kΩ and 40 kΩ) enable dual-stage TD resistance measurement in pre-startup, allowing hysteresis tuning while preserving valley-switching timing integrity.
Can ICC80QSGXUMA1 operate without an external start-up circuit?
Yes-it supports standard HV resistor start-up via VCC, but the TD pin's internal pull-up also enables optional active start-up circuits for faster VCC charging. In that configuration, TD controls external circuit enable/disable during soft-start and burst mode, improving startup reliability and reducing no-load losses.
What protection features are integrated into ICC80QSGXUMA1?
ICC80QSGXUMA1 integrates primary-side OCP, flyback output OVP, VCC OVP/UVP, internal OTP, open-loop protection, brownin/brownout, and input OVP. All protections feature auto-restart or latch-off behavior per configuration, with brownout level adaptively raised under high bus ripple to prevent transformer saturation.
