Part Number: TPS61040
Hi there,
I want to use the TPS61040 as a backlight driver (schematic as datasheet figure 21). During start-up there is a delay of 250us between setting the EN-pin to high and the switching of the power-MOSFET (SW-pin).
How are the 250us defined? What is the maximum delay I can expect the SW-pin to start switching?
As a backlight frequency I use 200Hz. This means that I always loose 5% of the brightness and has unwanted influence on the linearity of the brightness. Is there a way to shorten this start-up delay and also shorten the soft start?
Thanks for all feedback in advance.
Kind regards,
David
