TS19820CS

TS19820CS Taiwan Semiconductor Single-Stage Power Factor Correction Dimmable LED Driver with 3.3V Voltage Regulator Output DESCRIPTION FEATURES The TS19820 is a single-stage active power factor correction (PFC) switch-mode power supply IC supporting high PF over a wide AC input voltage range. Output current modulation dimming is controlled from a dedicated pin capable of either PWM or linear analog signal input. The TS19820 achieves high accuracy lineand load-regulation in discontinuous conduction mode (DCM) architecture. Output switching regulation is controlled with pulse frequency modulation (PFM) which is particularly suited for high conversion efficiency and high PF even at low output power levels. The TS19820 also features a 3.3V LDO output for MCU applications. Integrated protection features such as an external switching MOSFET gate drive voltage clamp, VCC over-voltage protection, and system output open/short circuit protection increase system reliability. ● ● ● ● ● ● ● ● ● ● ● ● ● SOP-8 Supports PWM & Linear dimming Embedded 3.3V LDO output for MCU Low cost BOM High Power Factor >0.9 Pulse Frequency Modulation (PFM) Control Discontinuous Conduction Mode Control No Opto-Coupler Required Gate output voltage clamp LED open and short protection Over Current Protection (OCP) Internal Over Temperature Protection (OTP) Low start-Up current Compliant to RoHS Directive 2011/65/EU and in accordance to WEEE 2002/96/EC. ● Halogen-Free according to IEC 61249-2-21 APPLICATION ● ● ● Smart LED lighting Infrared remote control light Motion sensing LED light Pin Definition: 1.
