TS19730
Single-Stage Low THD
Buck-Boost PWM Control LED Driver
1/7
Version: A15
SOT-26
Description
The TS19730 is a high power factor, low THD and high accuracy constant current PWM controller. TS19730
achieves high power factor and high efficiency by boundary current mode (BCM). The line and load regulation of
LED current are within ±2.5%. TS19730 also provides gate driving voltage clamping, VCC over-voltage protection,
and system output open/short circuit protection to increase IC performance.
Features
● Low THD <10%
● Constant Current Accuracy within ±2.5%
● High Power Factor >0.9
● Low BOM Cost
● Boundary Conduction Mode Control
● Gate Output Voltage Clamp
● LED Open Protection
● LED Short protection
● Over Current Protection (OCP)
● Over Thermal Protection (OTP)
Applications
● LED lighting
● Down light
● Tube lamp
● PAR lamp
● Bulb
