Other Parts Discussed in Thread: LP5523
Hi,
Is it possible to disable charge pump and omit capacitors connected to C1+ C1-, C2+ C2- and VOUT and connect VOUT to VDD (5 V) for LP5523(1)? I don't need charge pump as there is 5 V voltage present in my device to supply power for leds.
From datasheet I understood that logic levels are defined by EN voltage. Is that correct? I will interface this driver with 3V3 MCU so EN, SCL, SDA will be 3V3 logic levels.
Are all channels of this driver capable of supplying 25.5 mA simultaneously (if adequate cooling is provided - I guess QFN chip should have no problems with cooling when its pad is connected to ground plane)?
