TS19450

Taiwan Semiconductor

AC/DC WLED Driver with External MOSFET

Universal High Brightness

DESCRIPTION

FEATURES

The TS19450 is an open loop, current mode control

LED driver IC. It can be programmed to operate in

either a constant frequency or constant off-time mode.

It includes an 8V~450V linear regulator which allows it

to work from a wide range of input voltages without the

need for an external low voltage supply. The TS19450

includes a PWM dimming input that can accept an

external control signal with a duty ratio of 0~100% and

a frequency of up to a few kHz. It also includes a

0~250mV linear dimming input which can be used for

linear dimming of the LED current.

●

Switch mode controller for single switch LED

drivers

●

Open loop peak current controller

Internal 8V~450V linear regulator

Constant frequency or constant off-time operation

Linear and PWM dimming capability

Requires few external components for operation

APPLICATION

●

DC/DC or AC/DC LED driver applications

RGB backlighting LED driver

Back lighting of flat panel displays

General purpose constant current source

Signage and decorative LED lighting

Charger

The TS19450 is ideally suited for buck LED drivers.

Since it operates in open loop current mode control,

the controller achieves good output current

regulation without the need for any loop

compensation. PWM dimming response is limited

only by the rate of rise and fall of the inductor

current, enabling very fast rise and fall times. The

TS19450 requires only free external components

(apart from the power stage) to produce a controlled

LED current making it an ideal solution for low cost

LED drivers.
