# FC1350 LED Lighting Driver

## Description

️· A 350mA LED lighting driver capable of efficiently driving single or multiple series-connected LEDs.
️· Provides an adjustable output current of up to 350mA from a 7V to 32V input supply.
️· Utilizes an external resistor to set nominal average output current.
️· Allows for output current adjustment above or below set value via the 'ADJ' pin, accepting DC voltage or PWM signals.
️· Contains a PWM filter providing a soft-start feature.
️· Applying a voltage below 0.2V on the ADJ pin turns off the output and switches the device into a low-current standby state.

## Features

️· Built-in thermal and over-current shutdown.
️· Internal 32V Power MOS switch.
️· 350mA output current.
️· Single-pin on/off and dimming control via the ADJ pin (DC voltage or PWM).
️· Internal PWM filter.
️· Soft-start functionality.
️· Up to 90% efficiency.
️· 7V to 32V input voltage range.
️· 40V transient capability.
️· Output shutdown.
️· Up to 1MHz switching frequency.
️· Inherent open-circuit LED protection.
️· Typical 5% output current accuracy.

## Applications

️· MR16 and general lighting.
️· Automotive lighting.
️· Low voltage industrial lighting.
️· LED backlighting.
️· Illuminated signs.
