TS19720CX6 RFG

P1-P3P4-P6P7-P7
TS19720
Taiwan Semiconductor
1 Version: B15
Single-Stage PFC Buck Current Control LED Driver
DESCRIPTION
The TS19720 is a high power factor and high accuracy
constant current PWM controller. It is able to control
total harmonic distortion (THD) and efficiency
optimization by an external resistor. TS19720 achieves
high power factor and high efficiency by boundary
conduction mode (BCM). The line and load regulation of
LED current are within ±2.5%. TS19720 also provides
gate driving voltage clamping, V
CC
over-voltage
protection, and system output open/short circuit
protection to increase IC performance.
FEATURES
● Low THD <15%
● 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)
● Compliant to RoHS Directive 2011/65/EU and in
accordance to WEEE 2002/96/EC.
● Halogen-free according to IEC 61249-2-21
APPLICATION
● LED lighting
● Down lights, Tube lamps, PAR Lamps, Bulbs

Notes:
1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may
remain possibility to affect device reliability.
2. Devices are ESD sensitive. Handing precaution recommended..
3. The device is not guaranteed to function outside its operating conditions.
4. Guaranteed by design.
5. Auto Recovery Type.
