TPS92518QPWPRQ1

The TPS92518QPWPRQ1 from Texas Instruments is an integrated high-voltage LED driver suitable for general purpose applications. This driver includes a boost converter, switching voltage regulator and a current-dimming LED driver. It enables the user to control one or two LED output current paths. The driver is optimized for high efficiency and wide output voltage range.

The TPS92518QPWPRQ1 LED driver is ideal for automotive tail lamps and LED products. It operates over a range of supply voltages from 4.5 to 40V and can generate LED current levels up to 1.03A. Electronic current-dimming is supported through PWM and dimming range is varies from 0.1% to 100%, allowing for fine tuning of LED brightness. The driver is protected against current and voltage overshoots, and it can be used in vehicles with replacement of ignition switch and without capacitor.

The TPS92518QPWPRQ1 LED driver provides accurate current protection. The driver features over- and under-voltage protection that automatically disables the output when either over-voltage or under-voltage events occur, thus protecting the circuitry and LEDs. A calibrated current-sense threshold with independent control is also available.

The TPS92518QPWPRQ1 works on the principle of voltage regulation to regulate the output current. The device senses the output current and adjusts the reference voltage to maintain the output current level. This regulation eliminates any ripple voltage and provides a very stable and regulated current for the LEDs. Additionally, the voltage output limit is adjustable via external resistors. This makes the TPS92518QPWPRQ1 a highly functional and easy-to-use device.

The TPS92518QPWPRQ1 boasts high efficiency throughout its operating range of 0.15V to 40V, making it an ideal choice for automotive and industrial applications. The device has a low quiescent current of only 130nA and provides up to 95% efficiency. It also features extremely fast dynamic response, thus providing accurate current control.

The TPS92518QPWPRQ1 LED driver is suitable for car tail lamps, landscape lighting systems, & indoor/outdoor decorative LED lights. It provides highly efficient LED current control and enables LED dimming, without sacrificing accuracy or stability. It is designed to deliver reliable, cost-effective solutions with minimal component count and board space.
