TPS92519-Q1

The TPS92519-Q1 is a standalone, dual buck LED driver that can have each channel's current controlled by IADJ pins and be PWM dimmed by UDIM pins for each respective channel. The 5-V supply for V5D is used by both channels and the EN pin enables or disabled both channels to put the device in sleep mode. The FLT pins indicated if there is a short or open condition for each channel. Each channel controls the output current by applying a voltage from 0.14 to 2.4 V on the IADJx pins. Similarly, the PWM dimming for each channel is adjusted by applying the PWM signal to the UDIMx pins.
