DESCRIPTION

The VN1160, VN1160-1, VN1160T are a monolithic

device made by using STMicroelectronics VIPower

technology, intended for building a complete flashing unit

for two wheel vehicles. The device is connected between

the battery positive terminal (VCC pin) and a mechanical

switch to the right and/or left bulbs. As soon as the series

switch connects the OUT pin to the bulbs, the device

begins to turn on/off with a 50 duty cycle.

An external low voltage capacitor (220mF, 10V)

connected between the CEXT pin and the OUT pin

stores energy for powering the device during the ON

phase and sets the flashing frequency.

When a low load is detected (output current lower than

Idf), flashing frequency is automatically doubled.

VN1160属于集成电路（IC） > AC DC 转换器，离线开关。意法半导体（ST）集团制造生产的VN1160AC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。
