General Description

The FC1360 is a continuous mode inductive step-down converter, designed for driving single or multiple series

connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input

supply between 7V and 30V and provides an externally adjustable output current of up to 1A. Depending upon

supply voltage and external components, this can provide up to 24 watts of output power.

The FC1360 includes the output switch and a high-side output current sensing circuit, which uses an external

resistor to set the nominal average output current. Output current can be adjusted above, or below the set value,

by applying an external control signal to the 'ADJ' pin.

The PWM filter provides a soft-start feature by controlling the rise of input/output current. The soft-start time can

be increased using an external capacitor from the ADJ pin to ground. Applying a voltage of 0.2V or lower to the

ADJ pin turns the output off and switches the device into a low current standby state.
