Using L6599 STBY pin for power output control through PWM

Question asked by Adeesh Kale on Jun 26, 2017

Hi, I'm trying to design an LED driver using L6599 and L6533 (boost then LLC) stages, I'd like to know if I can use a 300Hz PWM on the STBY pin of 6599 to drive the output in a PWM dimming control? The datasheet doesn't specify the minimum time to come out of STBY low state for the chip. Note that I don't mean to put it in sleep so that it has to soft start, I just want to use the burst mode to my advantage. I'm thinking of synchronously having a shunt MOSFET to drain the low energy current when I've disabled the 6599. Thank you
