[原创] TI TPS92630－Q1汽车尾灯参考设计TIDA－00677

TI公司的TPS92630-Q1组合了高VIN DC/DC降压转换器和高VIN低压降(LDO)稳压器,满足汽车AEC-Q100标准,输入电压3.6-V到36-V,最大负载电流3.2A,输出可调电压1.1V-20V,可调开关频率100-kHz到2.5-MHz,主要用在汽车娱乐系统,高档驾驶辅助系统(ADAS),汽车远程通信,eCALL,12V/24V工业和商业低功耗系统.本文介绍了TPS92630-Q1主要特性,框图和两种应用案例,以及CISPR 25汽车尾灯参考设计TIDA-00677主要特性,框图,电路图,材料清单和PCB设计图.

The TPS65321-Q1 device is a combination of a high-VIN DC-DC step-down converter, referred to as the buck regulator, with an adjustable switch-mode frequency from 100-kHz to 2.5-MHz, and a high-VIN 280-mA low-dropout (LDO) regulator. The input range is 3.6-V to 36-V for the buck regulator, and 3-V to 36-V for the LDO regulator. The buck regulator has an integrated high-side MOSFET and an active-low, open-drain power-good output-pin (nRST). The LDO regulator also has an integrated MOSFET and features a low-input supply current of 35-μA typical in no-load condition. The low-voltage tracking feature enables the TPS65321-Q1 device to track the input supply during cold-crank conditions.
