EVALTDA388251VOUTTOBO1

EVALTDA388251VOUTTOBO1 is an evaluation board to evaluate TDA38825 synchronous buck regulator, providing a compact, high-performance and flexible solution in a small 3mm x 4mm QFN package. Key features offered by the TDA38825 include internal soft-start, precision 0.6V reference voltage, power good, thermal protection, programmable switching frequency in the range of 600kHz to 1MHz, programmable soft-start, enable input, input undervoltage lockout (UVLO) for proper start-up, latched-off output overvoltage protection (OVP), overcurrent protection (OCP) limit, and pre-bias start-up.
