Richtek RT9302GJ8

线性2.8V5.5V20mA

Overview

The RT9302GJ8 is a high performance constant current driver for white LED. It supports up to 3 white LEDs and regulates a constant current for uniform intensity. Each channel supports up to 20mA output current with 1% typical current accuracy and 0.7% typical current matching. The RT9302GJ8 provides a 16-step brightness dimming control. The LED current can be easily configured from 1.25mA to 20mA. The dimming of white LEDs' current can be achieved by applying a pulse signal to the EN pin. The LED current can be turned off by EN pin with pull low for 20μs or longer. The typical leakage current is 4μA while shutdown condition.RT9302GJ8 is available in a TSOT-23-8 package (1.0mm maximum height).
