[bwin中国可以用吗? ] TI TIDA－01375汽车日灯(DRL)和位置灯参考设计

TI公司的TIDA-01375是采用TPS92830-Q1线性LED控制器的汽车日运营灯(DRL)和位置灯参考设计,采用相同的LED可实现两种功能,具有良好的EMC性能,全保护和诊断.本文介绍了参考设计TIDA-01375主要特性,框图,电路图,材料清单和PCB设计图.

This reference design details a solution for an automotive daytime running light (DRL) and position light. The TPS92830-Q1 linear LED controller used in this design is directly supplied from the automotive battery, allowing you to use the same LEDs for both functions. This reference design also features good EMC performance, full protection and diagnostics.

Automotive DRLs and position lights often reuse the same LEDs with two levels of brightness. Thisreference design offers a dual-brightness solution for DRL and position light reuse applications using theintegrated pulse-width modulation (PWM) generator of the TPS92830-Q1 controller. Using linear devices,this design has a satisfactory EMC performance that meets CISPR 25 Class-5 conducted emission andradiated emission standards and passes the ISO11452-4 bulk current injection (BCI) test.
