Please rest assured to buy our products! ال TPS92691QPWPRQ1 device is an automotive multi-topology LED driver with rail-to-rail current sense amplifiers. It is a product independently researched and developed by Texas Instruments. XT-ShenZhen provides you with TPS92691QPWPRQ1 device, رجاء أترك لنا رسالة! We will reply within 24 ساعات!

The TPS92691QPWPRQ1 device is a general-purpose LED controller supporting a range of boost or buck driver topologies. The device features a fixed frequency peak current mode control technique with programmable switching frequency, slope compensation and soft-start timing.
It incorporates a high-voltage (65 الخامس) rail-to-rail current sense amplifier, allowing LED current to be measured directly through a high-side or low-side series sense resistor.
The TPS92691QPWPRQ1 device can also continuously monitor the state of the LED through a current monitor output. It is possible to detect and protect the short circuit or open circuit of the LED. Additional fault protection features are VCC UVLO, output overvoltage protection (OVP), switch cycle-by-cycle current limit, and thermal protection.
