VN1160集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)規(guī)格書PDF中文資料

VN1160屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由意法半導體集團制造生產(chǎn)的VN1160AC DC 轉(zhuǎn)換器，離線開關(guān)該系列是元器件級控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)換為直流電（通常電壓大幅降低）的設(shè)備。集成和未集成系統(tǒng)主要開關(guān)元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來實現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標題。

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.
