Product details

Overview

TDA16888 from Infineon Technologies is a high-performance PWM+PFC combi controller IC for off-line SMPS, integrating synchronized PFC (boost/flyback) and PWM (forward/flyback) control sections in one monolithic device. It delivers 94% max PFC duty cycle, 50% max PWM duty cycle to prevent transformer saturation, 15 mA quiescent current, and operates from 90–270 V_AC input with internal 15–200 kHz oscillator.

For engineers reviewing the TDA16888 datasheet, TDA16888 pinout, TDA16888 application, or TDA16888 equivalent, key selection considerations include dual-loop average-current-mode PFC control, externally synchronizable fixed-frequency operation, integrated overvoltage/undervoltage protection, and separate soft-start and shutdown controls for both PFC and PWM stages.

Technical Context

The TDA16888 implements two independent yet internally synchronized control loops: the PFC section uses leading-edge PWM with average current sensing (via PFC CS and PFC IAC) and voltage feedback (PFC FB), supporting continuous/discontinuous conduction modes; the PWM section employs trailing-edge current-mode control with ramp compensation (PWM RMP) and output voltage regulation (PWM IN).

Its protection architecture includes fast overvoltage detection at PFC VS (pin 19) that shuts down both outputs, auxiliary undervoltage shutdown of PWM when PFC output sags, and ESD-hardened pins with internal Zener clamping at VCC (pin 9) up to 17.5 V. Power management enables internal stand-by below 11 V and transitions to full operation above 14 V.

Key Specifications

Parameter	Value and Actual Design Meaning
PFC Max Duty Cycle	94% - Enables minimal line current gaps in boost/flyback PFC preconverters
PWM Max Duty Cycle	50% - Prevents core saturation in forward/flyback transformer designs
Oscillator Range	15–200 kHz - Internally set via ROSC pin; externally synchronizable via SYNC pin
Quiescent Current	15 mA - Low operating current supports high-efficiency power supply design
Start-up Supply Current	50 µA - Enables reliable start-up from high-impedance auxiliary supplies
UVLO Thresholds	11 V (disable), 14 V (enable) - Hysteresis ensures stable power management during brownouts
Gate Drive Output	1 A (totem-pole) - Directly drives MOSFET gates without external buffers in typical PFC/PWM stages

Pinout & Package

Available in P-DIP-20-5 (through-hole) and P-DSO-20-1 (surface-mount) packages, both 20-pin with identical pin mapping and thermal pad on DSO variant.

Pin/Terminal	Circuit Role	Design Meaning
1 PFC IAC	AC line voltage sensing input	Feeds rectified AC waveform to multiplier for sinusoidal current shaping
2 VREF	7.5 V reference output	Stable reference for external circuitry; foldback-limited during short-circuit
8 PFC OUT	PFC gate driver output	1 A totem-pole output driving PFC switch (e.g., CoolMOS™)
10 PWM OUT	PWM gate driver output	1 A totem-pole output driving PWM switch (e.g., flyback MOSFET)
19 PFC VS	PFC output voltage sense	Primary overvoltage/undervoltage protection trigger point for both sections
13 PWM SS	PWM soft-start control	Capacitor-based ramp to limit inrush current during power-up

Key Features

Feature	Design Value
Dual-loop PFC control	Average current + voltage feedback enables >0.99 PF and low THD across universal AC input
Internally synchronized PFC/PWM	Eliminates external clock sync components and reduces timing skew between stages
Independent shutdown capability	External short of VREF to GND disables both PFC OUT and PWM OUT simultaneously
Noise-immune current sensing	Peak current limitation with filtering at PFC CS and PWM CS prevents false triggering
Safe-fail protection logic	Broken-wire detection at PFC VS forces immediate PFC OUT disable to prevent uncontrolled rise

Applications

LED Driver Power Supply

Industrial AC-DC Adapter

Use Scenario: Constant-power LED driver for street lighting with universal AC input (90–270 V_AC).

IC Role / Device Role / Timing Role: Dual-stage controller managing boost PFC followed by flyback PWM to deliver regulated DC current.

Use Value: 94% PFC duty cycle maintains high efficiency across wide input range; 50% PWM duty cap avoids transformer saturation under load transients.

Use Scenario: 100 W industrial adapter powering PLC I/O modules with strict IEC 61000-3-2 Class C compliance.

IC Role / Device Role / Timing Role: Integrated PFC+PWM controller enabling single-chip compliance with harmonic current limits.

Use Value: Average-current-mode PFC achieves <30% THD; internal 15–200 kHz oscillator allows EMI optimization via frequency tuning.

Server PSU Front-End

Medical Imaging Power Module

Use Scenario: High-density front-end for 3 kW server PSU requiring compact, thermally efficient PFC+PWM integration.

IC Role / Device Role / Timing Role: Primary controller for interleaved boost PFC stage and LLC-resonant PWM stage (using flyback-derived bias).

Use Value: 1 A gate drive eliminates external drivers; 50 µA start-up current enables reliable cold-start from standby rail.

Use Scenario: Auxiliary power module for MRI gradient amplifier subsystems requiring high reliability and low EMI.

IC Role / Device Role / Timing Role: Isolated dual-output supply controller delivering clean ±15 V and +5 V from mains with reinforced insulation.

Use Value: Dual UVLO thresholds (11 V/14 V) ensure graceful shutdown during brownouts; broken-wire detection prevents hazardous open-circuit faults.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PFC+PWM combi controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE2PCS01	Single-stage transition-mode PFC only; no integrated PWM section	Requires external PWM controller for two-stage topologies	Select when PFC-only function suffices or when PWM stage demands higher peak current than 1 A
UCC28070	Interleaved dual-channel CCM PFC controller; no PWM section	Designed for high-power (>300 W) PFC only; needs companion PWM IC	Choose for >500 W systems where interleaving reduces input ripple and EMI

Compared with ICE2PCS01 and UCC28070, the TDA16888 uniquely integrates synchronized PFC and PWM control in one package-reducing BOM count, PCB area, and timing coordination complexity-while maintaining discrete-level flexibility in topology selection (boost/flyback PFC, forward/flyback PWM).

FAQ

What is the maximum recommended operating frequency for the TDA16888's internal oscillator?

The TDA16888 supports an internally set oscillator frequency range from 15 kHz to 200 kHz, configured via an external resistor on the ROSC pin. Operation above 200 kHz is not specified and may compromise stability or protection response time due to internal propagation delays.

Can the PFC and PWM sections operate at different frequencies?

No-the PFC and PWM sections are internally synchronized and must operate at the same switching frequency. External synchronization via the SYNC pin affects both sections simultaneously; independent frequency control is not supported.

How does the TDA16888 handle PFC output undervoltage conditions?

When PFC VS (pin 19) falls below the threshold set by comparator C4, the PWM section is immediately disabled to reduce load and allow PFC output voltage recovery. This action occurs before the main UVLO triggers, ensuring system stability without full shutdown.

Is the TDA16888 qualified for use in life-support equipment?

No-Infineon explicitly restricts use in life-support devices unless expressly approved in writing. The device lacks the required safety certifications (e.g., ISO 13485, IEC 61508 SIL-3) and fault coverage for implantable or critical-care applications.
