TS19450
Taiwan Semiconductor
AC/DC WLED Driver with External MOSFET Universal High Brightness
DESCRIPTION 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.
The TS19450 is ideally suited f...
