To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

Description

The FL6300A lighting power controller includes a highly integrated PWM controller and provides several features to enhance the performance of flyback converters in medium- to high-power lumens applications. The FL6300A is applied on quasi-resonant flyback converters, where maximum operating frequency is limited to below 100 kHz. A built-in HV startup circuit can provide more startup cu rrent to reduce the startup time of the controller. Once the V DD voltage exceeds the turn-on threshold voltage, the HV startup function is disabled to reduce power consumption. An internal valley voltage detector ensures that the power system operates at quasi-resonant o peration over a wide-range of line voltage and load conditions, as well as reducing switching loss to minimize switching voltage on the drain of the power MOSFET. To minimize standby power consumption and improve light-load efficiency, a proprietary Green-Mode function provides off-time modulation to decrease switching frequency and perform extended valley voltage switching to keep to a minimum switching pulse. The operating frequency is limited by minimum t OFF time, which is 38 µs to 8 µs. FL6300A also provides many protection functions. Pulse-by-pulse current limit ing ensures the fixed-peak current-limit level, even when a short circuit occurs. Once an open-circuit failure occurs in the feedback loop, the internal protection circuit disables PWM output immediately. When V DD drops below the turn-off threshold voltage, the cont roller disables PWM output. The gate output is clamped at 18 V to protect the power MOSFET from high gate-source voltage conditions. The minimum tOFF time limit prevents the system frequency from being too high. When over-voltage protection (OVP) is triggered by DET or when internal over- temperature protection (OTP ) is triggered, the power system enters Latch Mode until AC power is removed.
