TS19720
Taiwan Semiconductor
Signal-Stage PFC Buck Current Control LED Driver
DESCRIPTION
FEATURES
The TS19720 is a high power factor and high accuracy ● Low THD <15%
constant current PWM controller. It is able to control ● Constant Current Accuracy within ±2.5%
total harmonic distortion (THD) and efficiency ● High Power Factor >0.9
optimization by an external resistor. TS19720 achieves ● Low BOM Cost
high power factor and high efficiency by boundary ● Boundary Conduction Mode Control
conduction mode (BCM). The line and load regulation of ● Gate Output Voltage Clamp
LED current are within ±2.5%. TS19720 also provides ● LED Open Protection
gate driving voltage clamping, V_CC over-voltage ● LED Short Protection
protection, and system output open/short circuit ● Over Current Protection (OCP)
protection to increase IC performance.
● Over Thermal Protection (OTP)
APPLICATION
● LED lighting
● Down light
● Tube lamp
● PAR lamp
● Bulb
