LED DRIVING CIRCUIT PACKAGE

摘要

An LED driving circuit package comprises a rectification unit, an LED driving switch unit, and a low voltage control unit. The rectification unit receives voltage of AC power and generates aneurysm voltage by rectifying the voltage of the AC power. The LED driving switch unit comprises a plurality of switch units and a plurality of current control units. The low voltage control unit comprises a circuit power supply unit, a voltage detection unit, a reference frequency generation unit, and a reference pulse generation unit. The circuit power supply unit generates low voltage power. The voltage detection unit detects the size of the aneurysm voltage. The reference frequency generation unit generates a reference frequency by using the low voltage power generated by the circuit power supply unit. The reference pulse generation unit generates a reference pulse to control the operation of the LED driving switch unit according to the reference frequency and the size of the voltage detected in the voltage detection unit. The reference pulse generation unit operates by using the low voltage power generated by the circuit power supply unit.
