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. 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.
