Product details
Overview
TDA16888GGEGHUMA1 from Infineon Technologies is a high-performance PWM+PFC combi controller IC for off-line SMPS, integrating dual-loop average-current-mode PFC and current-mode PWM in a single 20-pin DSO package. It supports boost/flyback PFC (94% max duty cycle) and forward/flyback PWM (50% max duty cycle), operates from 90–270 VAC input, delivers 7.5 V reference, and features internal 15–200 kHz oscillator with external sync capability.
For engineers reviewing the TDA16888GGEGHUMA1 datasheet, TDA16888GGEGHUMA1 pinout, TDA16888GGEGHUMA1 application, or TDA16888GGEGHUMA1 equivalent, key selection criteria include IEC 1000-3 compliance, dual gate drivers (1 A each), undervoltage lockout (11 V/14 V thresholds), auxiliary supply sensing, and synchronized PFC-PWM timing to minimize line current distortion.
Technical Context
The TDA16888GGEGHUMA1 implements internally synchronized dual-control architecture: the PFC section uses leading-edge PWM with average-current + voltage feedback, while the PWM section employs trailing-edge current-mode control with soft-start management. Both sections share a common oscillator (pin 16 ROSC) and support external synchronization (pin 12 SYNC).
Protection logic includes fast overvoltage shutdown triggered at PFC VS (pin 19), undervoltage-induced PWM disable below PFC output threshold, broken-wire detection on PFC VS and GND pins, and external shutdown via VREF (pin 2) shorting - all coordinated through integrated bias control and power management circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PFC Max Duty Cycle | 94% - enables near-continuous conduction mode for minimal line current THD in boost/flyback preconverters |
| PWM Max Duty Cycle | 50% - prevents transformer core saturation in forward converter topologies |
| Oscillator Range | 15–200 kHz - set by external ROSC resistor; allows EMI optimization and thermal trade-off tuning |
| VREF Output | 7.5 V ±1% - stable precision reference for external feedback dividers and auxiliary circuit biasing |
| Start-up Current | 50 µA typical - enables low-power auxiliary winding startup without dedicated start-up circuitry |
| Quiescent Current | 15 mA - defines minimum operating power draw during regulation, critical for light-load efficiency |
| UVLO Thresholds | 11 V (disable), 14 V (enable) - hysteresis ensures clean power-on/power-off sequencing without oscillation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-integration PFC+PWM controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2PCS01 | Single-channel PFC-only controller; requires external PWM IC; no integrated PWM gate driver or sync logic | Used in cost-sensitive designs where PFC and PWM stages are decoupled or require independent optimization | Select when modular control, separate thermal management, or legacy PWM IC reuse is required |
| UCC28070 | Interleaved dual-phase PFC controller only; no PWM section; higher channel count but no integrated DC-DC control | Targeted at high-power (>500 W) PFC front-ends with strict THD limits; needs companion PWM IC like UCC2891 | Select for >300 W applications needing interleaving benefits and discrete PWM flexibility |
Compared with ICE2PCS01 and UCC28070, the TDA16888GGEGHUMA1 uniquely integrates synchronized PFC+PWM control in one die, reducing BOM count and PCB area while ensuring timing coherence-critical for compact, high-density 100–300 W off-line supplies.

FAQ
What is the maximum allowable voltage on VCC (pin 9) before internal clamping activates?
The internal Zener diode at pin 9 (VCC) clamps voltages above 17.5 V to protect the IC. Operation is guaranteed between 11 V and 17.5 V; sustained exposure above 17.5 V risks permanent damage even with clamping. External RC snubbers or TVS devices are recommended for transient overvoltage events exceeding this rating.
Can the TDA16888GGEGHUMA1 operate in discontinuous conduction mode (DCM) for the PFC stage?
Yes - the datasheet explicitly states that both continuous and discontinuous conduction modes are supported for the PFC preconverter. The average-current-mode control architecture adapts to DCM operation, though efficiency and THD performance are optimized in CCM. Designers must adjust current-sense gain and compensation to maintain stability in DCM.
How does the auxiliary supply sensing (AUX VS, pin 20) interact with startup behavior?
Pin 20 monitors auxiliary winding voltage to confirm sufficient bias supply before enabling full operation. If AUX VS falls below its internal threshold during startup, the IC remains in low-current stand-by mode - preventing erratic PWM/PFC activation. This ensures reliable self-biasing from the transformer auxiliary winding without external start-up circuitry.
Is external synchronization mandatory, or can the internal oscillator be used standalone?
The internal oscillator (set by ROSC resistor on pin 16) operates standalone without external sync. Pin 12 (SYNC) is optional: applying an external clock overrides the internal frequency and phase-aligns PFC and PWM switching - beneficial for EMI reduction but not required for basic functionality.
