TPS92641EVM .

The TPS92641EVM evaluation module contains TPS92641 IC configured as a WLED power solution providing a single channel regulated current output. The TPS92641 is a high voltage, synchronous NFET controller for buck current regulators. Output current regulation is based on valley current mode operation using a controlled ontime architecture. This control method eases the design of loop compensation while maintaining nearly constant switching frequency. This evaluation module accepts logic level PWM dimming or analogy dimming control input. A high efficiency single inductor synchronous step down (buck) converter topology is used. The current output is ideal for driving a WLED light bar in architecture lighting applications.

• Input voltage range from 43V to 53V
• Drive 10 LEDs in series at 1A
• High efficiency sync. rect. buck
• Current regulation within 3%
• Support PWM dimming
