Product Description

PT6901 is an open loop current mode control high brightness LED driver IC. PT6901 can be programmed to operate in either constant frequency or constant off-time mode. The frequency can be programmable set as 30KHz~300KHz. The PT6901 is ideally suited
for buck LED drivers. It exports PWM signal to control the external MOS. The PT6901 supply voltage input range is from 8V to 12V, and the output current can be programmed between a few milliamps and up to more than 1.0A. PT6901 can drive a single or multiple series
LEDs, and provide reliability constant current output by detecting LED peak current.

The functions of linear and PWM dimming are included. PT6901 provides a low-frequency PWM dimming input that can accept an external control signal with a duty cycle of 0~100% and a frequency
between 100Hz and a few KHz. Output current to LED string can be programmed to any value between 0 to its maximum value at the PWM dimming control input of PT6901. Also, a 0~240mV linear dimming input can be used for linear dimming of the LED current.
