Product Introduction

Overview

The TPS61193-Q1, produced by Texas Instruments, is a highly integrated, high-efficiency, and low-EMI LED driver designed specifically for automotive and industrial applications. This device features three high-precision current sinks, each capable of driving up to 100 mA per channel, with an option to combine outputs for higher current capability. The TPS61193-Q1 supports both boost and SEPIC mode operation, with an adaptive output voltage control that minimizes power consumption by adjusting the voltage to the lowest sufficient level. It is qualified for automotive applications, meeting AEC-Q100 standards with an ambient operating temperature range of -40°C to +125°C.
