Product Description

PT6904 is a constant-current LED driver IC utilized constant frequency, controls buck, boost or buck-boost switch converter. In each control mode, PT6904 adopts the inductance current continuous conduction, peak current control mode and the feedback of the output current. It’s controlled by the internal transconductance operational amplifier and
external adjustable slope compensation, it is able to gain the high precision output current in closed loop.

The typical functions of PT6904 such as UVLO (Under Voltage Lockout), input current limit, open LED protection, output short circuit protection, output current precision control, linear dimming, PWM
dimming, etc. In addition, multiple the sync pin of PT6904s or input the same clock signal, these ICs will operate on the same frequency.

Input voltage of PT6904 is 9V to 36V, the oscillator frequency is 25KHz~350KHz that setting by the external resistors, and the output PWM signal drive external power NMOS. PWM dimming input can
accept an external control signal with a duty cycle 0~100% and a frequency between 100Hz to a few KHz.
