Inverter Fluorescent Lamp
详情介绍
Overview
Renesas product lineup includes the R8C Family of 8/16-bit MCUs with on-chip PWM (Pulse Width Modulation) generation and output functions. In particular, the 78K0 Series and the R8C/2x Series of MCUs integrate dimmer inverter control, PFC (Power Factor Correction) on/off control, and DALI communication functions, and are ideal for inverter fluorescent lamp applications such as ceiling-recessed fixtures that are compact and lightweight while consuming little power.
