I have poor knowledge about synchronous FET Dimmig.
I don't understand about "dimming range of 16:1".
Could you please explain about this?
In data sheet,
7.3.6 Analog Dimming and Forced Continuous Conduction Mode
Analog dimming is accomplished by the SPI interface through the adjustment of the 10-bit CHxIADJ registers.
The TPS92520-Q1 improves the linear range of analog dimming by supporting forced continuous conduction mode of operation.
With synchronous MOSFETs, the inductor current is allowed to go negative for part of the switching cycle,
thus enabling linear dimming with over 16:1 dimming range.
