功能描述：

The ON8350 is a step down constant current high brightness LED driver

which provide a cost effective design  solution for automotive

interior/exterior lighting, architectural and ambient  lighting, LED

bulbs, and other LED illumination applications.

The ON8350operate from a  6.0V to 30V input voltage range. A high-side

current-sense resistor adjusts  the output current up to 1A and a

dedicated DIM input accepts either a DC  voltage or a wide range of pulsed

dimming. Applying a voltage of0.3V or lower  to the DIM pin turns the

output off and switches the device intoa low current  standby state.

A hysteretic control method ensures excellent input supply  rejection and

fast response during load transients and PWM dimming.

应用范围：

◆Architecture Detail lighting
◆Constant Current Source
◆Hand-held lighting
◆Portable Consumer Devices
