7 / 12 page  TCA62735AFLG TENTATIVE This datasheet is tentative, the values and contents are subject to change without any notice. 2005-04-26 (Page 7 of 12) Method of Current Dimming control 1) Input PWM signal to SHDN terminal ILED can be set according to the next expression. fPWM will recommend 100Hz. *In this PWM control operation, This IC repeats ON/OFF. In this result, rush current is occur when ON timing with supplying charge to C2OUT. Please note it. 0.61[V] × 400 × ON Duty[%] RSET[kΩ] ILED[mA] = C1- C2- C2+ GND CTL2 CTL1 CTL0 EN RSET=12kΩ CIN=2.2µF COUT=1.0µF C1=1.0µF VIN=3.6V PWM signal fPWM=100Hz, ON Duty50% C2=1.0µF Ch1 : VPWM Ch2 : IIN Ch3 : VOUT Ch4 : IOUT PWM Duty vs .
