Description
The TPS92643EVM-204 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS92643-Q1 3.0-A buck switching regulator designed for high-current LED drive applications. The TPS92643-Q1 is designed to control high-brightness light-emitting diodes (LED) and features a wide input voltage range (5.5 V to 40 V), PWM dimming capability, analog dimming capability, input under-voltage protection, fault detection, an internal 5-V regulator, and the ability to perform duty cycle control of the onboard 1.4-kHz PMW signal.
Features
- Supports 5.5-V to 40-V input (13-V nominal)
- Up to 3.0-A continuous with 4% accuracy
- Precision analog and PWM dimming
- LED short circuit, open circuit, and cable harness fault detection and indication
Typical applications
- Automotive LED drivers
