Combination Power Factor
Correction and
Quasi-Resonant Flyback
Controllers for LED Lighting
This combination IC integrates power factor correction (PFC) and
quasi−resonant flyback functionality necessary to implement a
compact and highly efficient LED driver for high performance LED
lighting applications.
The PFC stage utilizes a proprietary multiplier architecture to
achieve low harmonic distortion and near−unity power factor while
operating in a Critical Conduction Mode (CrM). The circuit
incorporates all the features necessary for building a robust and
compact PFC stage while minimizing the number of external
components.
The quasi−resonant current−mode flyback stage features a
proprietary valley−lockout circuitry, ensuring stable valley switching.
This system works down to the 4th valley and toggles to a frequency
foldback mode with a minimum frequency clamp beyond the 4th
valley to eliminate audible noise. Skip mode operation allows
excellent efficiency in light load conditions while consuming very low
standby power consumption.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device
functionality should not be assumed, damage may occur and reliability may be affected.
1. VPCS/PZCD(MAX) is the maximum voltage of the pin shown in the electrical table. When the voltage on this pin exceeds 5 V, the pin sinks
a current equal to (VPCS/PZCD − 5 V)/(2 kW). A VPSC/PZCD of 7 V generates a sink current of approximately 1 mA.
2. Maximum driver voltage is limited by the driver clamp voltage, VXDRV(high2), when VCC exceeds the driver clamp voltage. Otherwise,
the maximum driver voltage is VCC.
3. Maximum Ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond
those indicated may adversely affect device reliability. Functional operation under absolute maximum–rated conditions is not implied.
Functional operation should be restricted to the Recommended Operating Conditions.
4. This device contains Latch−up protection and has been tested per JEDEC JESD78D, Class I and exceeds +100/−100 mA.
5. Low Conductivity Board. As mounted on 80 x 100 x 1.5 mm FR4 substrate with a single layer of 50 mm2 of 2 oz copper traces and heat
spreading area. As specified for a JEDEC51−1 conductivity test PCB. Test conditions were under natural convection of zero air flow.
6. Pin 1 is rated to the maximum voltage of the part, or 700 V.
