EVALTDA388261VOUTTOBO1

EVALTDA388261VOUTTOBO1 is an evaluation board to evaluate TDA38826 synchronous buck regulator, providing a compact, high-performance, and flexible solution in a small 3 mm x 4 mm QFN package. Key features offered by the TDA38826 include internal soft-start, precision 0.9V reference voltage, power good, thermal protection, programmable switching frequency in the range of 600KHz to 1MHz, enable input, input undervoltage lockout (UVLO) for proper start-up, latched-off overvoltage protection (OVP), latched off overcurrent protection (OCP), and pre-bias start-up.
