I am looking for a leddriver for HB RGBW leds that is capable of:
- Driving > 1A < 1.5A
- High speed dimming (>350 Khz) (sounds strange but necessary)
- Protected against open circuit and short circuit.
- Common anode or common cathode (number of wires is important)
- I looked at LM3429, but cannot figure out common anode/cathode
- I looked at LM3434, but uncertain about dimming speed
I used Cypress CY8CLED04G01 uptil now, but need to use external drivers because MCU gets too small.
Would be nice to get some suggestions.
