1. Overview

CS6583 is a single-inductor non-isolated step-down LED constant current driver circuit that works when the inductor current is critically continuous.

mode. Suitable for full voltage input range of 85Vac~265Vac. The operating current of the circuit is extremely low and only a small amount of

peripheral components. In a large range, the output current of the system has nothing to do with the inductance. The circuit has excellent linear adjustment

rate and load regulation rate, reducing system costs.

CS6583 is mainly used in LED candle lights, LED bulbs and other LED lighting fields.

Its characteristics are as follows:

●Single inductor non-isolated buck structure

●Ultra-low operating current

●Wide input voltage

● Internally integrated 500V high-voltage power MOSFET

● ±5% LED output current accuracy

● LED open/short circuit protection

● CS short circuit protection

● Over-temperature protection function

● Package form: SOP8 (CS6583BBO, CS6583BO, CS6583CBO, CS6583DBO);
