TS19820CS - Single-Stage Power Factor Correction Dimmable LED Driver

Taiwan Semiconductor

General Description

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.

Key Features

a 3.3V LDO output for MCU.

TS19820CS Taiwan Semiconductor Single-Stage Power Factor Correction Dimmable LED Driver with 3.3V Voltage Regulator Output DESCRIPTION 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 line- and 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.
