Hi Clinton,

As last responses. Could you help provide reference schematic and explain relationship about "If really needed an offset can be added to the TPS92515 CSN to create a similar function."? 

Since I confuse why MAXIM device design 0.2V on IADJ .

    Hello Kuo,

    A resistor needs to be placed between the CS resistor and the CS pin. If the input voltage is fixed another resistor from CSN to GND would create a slight offset on CSN. If the input voltage varies then it will require two additional components for a total of four, three resistors and a zener diode.

    Another alternative is to place a large value resistor across the LEDs to prevent current from going to the LEDs when Iadj is zero.

    Maxim just designed their part different than TI.

    Regards,
