TPS92692QPWPRQ1

The TPS92692QPWPRQ1 is a high-accuracy automotive LED controller developed by Texas Instruments (TI). It uses peak current-mode control to support multiple switching LED driver topologies, including boost, buck, buck-boost, SEPIC, and flyback configurations. Designed for precision LED current regulation, this controller provides flexible dimming capabilities, improved electromagnetic interference (EMI) performance, and comprehensive fault monitoring for automotive and general lighting applications.

With a wide input voltage range of 4.5V to 65V, the TPS92692QPWPRQ1 supports demanding LED lighting systems that require stable current control and reliable operation. Its spread spectrum frequency modulation helps reduce EMI, while integrated analog and PWM dimming functions allow flexible brightness adjustment.

The TPS92692QPWPRQ1 offers better than ±4% LED current accuracy over a junction temperature range of -40°C to 150°C. Its direct PWM dimming interface supports a dimming range greater than 1000:1, while the analog current adjustment input provides a contrast ratio greater than 15:1. Additional features include an internal PWM generator, spread spectrum frequency modulation, an integrated P-channel MOSFET gate driver, and comprehensive LED fault detection. The device also provides current monitoring and fault indication to help identify LED overcurrent, output overvoltage, and output undervoltage conditions.

The TPS92692QPWPRQ1 is suitable for automotive exterior lighting systems, including LED headlamps, daytime running lights (DRLs), and other vehicle lighting applications. It can also be used in driver monitoring systems (DMS), LED general lighting, emergency lighting, and exit sign systems. Its flexible power conversion architecture and precise LED current regulation make it suitable for lighting designs requiring adjustable brightness, efficient power management, and reliable LED operation.
