Key Features
- Transition-mode (boundary-mode) PFC control with zero-current detection enables naturally low switching losses and simple magnetics design in boost PFC stages up to several hundred watts
- 600 mA peak gate drive output with both source and sink capability allows direct drive of medium-sized power MOSFETs without external driver buffers
- Integrated multiplier and voltage-error amplifier with 600 kHz maximum oscillator frequency support wide input voltage range designs from universal AC line 85 VAC to 265 VAC
Applications
The L6564D is used as the main PFC pre-regulator controller in offline switching power supplies such as PC ATX PSUs, LCD TV power modules, and industrial SMPS requiring IEC 61000-3-2 Class D harmonic compliance. Its transition-mode operation naturally achieves near-unity power factor at light-to-medium load levels, making it especially effective in compact adapters and lighting ballasts up to 300 W. The device integrates all necessary feedback, compensation, and protection functions to build a complete PFC stage with minimal external components.

Frequently Asked Questions
What control technique does the L6564D use and why is it beneficial for PFC designs?
The L6564D implements transition-mode (boundary conduction mode) PWM current-mode control. In this mode, the next switching cycle begins exactly when the inductor current reaches zero, eliminating reverse-recovery losses in the boost diode and reducing switching losses, allowing efficient PFC operation at output powers up to approximately 300 W.
How much gate drive current can L6564D deliver, and what MOSFET sizes does this support?
The L6564D provides a peak gate drive current of 600 mA (source and sink), sufficient to directly drive MOSFETs with gate charge up to about 60 nC at typical switching frequencies of 50 kHz to 200 kHz without an external gate driver stage, simplifying board layout and reducing component count.
What input supply voltage range is required to power the L6564D controller itself?
The L6564D VCC supply pin operates between 10.3 V minimum and 22.5 V maximum, with a nominal 12 V operating point. An under-voltage lockout (UVLO) threshold at approximately 10.3 V prevents erratic gate pulses during start-up before the auxiliary supply stabilizes.
Which end-product applications benefit most from using the L6564D as a PFC controller?
The L6564D is best suited for offline power supplies in the 50 W to 300 W range that must comply with IEC 61000-3-2 harmonic limits, including laptop adapters, LCD TV power boards, server auxiliary supplies, and LED street-lighting drivers operating from universal AC input of 85 VAC to 265 VAC.
