The RT4832 is an integrated total power solution for Flash LED Driver, Backlight WLED Driver, and DSV Driver. Flash LED Driver provides up to 2-CH 1.5A applications. Back Light WLED Driver supports up to 36V output for 10 WLEDs applications. And it provides 1024 steps LED current with logarithmic/linear curve. DSV is implemented by one single inductor boost and inverting charge pump, which provide customers minimum EVB area compared to dual inductors. The negative output power (CPOUT) comes from boost output (LCMOUT). It also provides DSV positive voltage (POS), which power noise is reduce by passing though LDO. Their ranges can be programmed from ±4V to ±6V per 50mV step respectively. Flash Boost Converter operates at 2MHz/4MHz frequency.资料下载
