Texas Instruments LM51772EVM-HP Evaluation Module
Texas Instruments LM51772EVM-HP Evaluation Module is designed to demonstrate the performance of LM51772, a wide-VIN high-power buck-boost controller. This module operates at a 9V to 48V input voltage range and 600kHz default switching frequency. The LM51772EVM-HP module provides a regulated output voltage when the input voltage is higher, equal, or lower than the adjusted output voltage. This evaluation module features optional Synchronization (SYNC), programmable input Under-Voltage Lock-Out (UVLO), output Constant Voltage (CV), and Constant Current (CC) options. Typical applications include wireless charging, industrial and rugged PCs, docking stations, Battery Backup Units (BBU), merchant DC/DC, and USB type-C® power delivery.
