The MP9473 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. It offers a compact solution to achieve a 3.5A, continuous-output current over a wide input-supply range with excellent load and line regulation. It provides fast, transient response and good stability for wide input-supply and load range. The MP9473 operates at high efficiency over a wide-output-current load range. MP9473 has full protection features including, short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown (TSD). The MP9473 requires minimal, readily available, standard, external components, and is available in a compact 3mmx4mm, 20-pin, QFN package.
The EV9473-L-00A is an evaluation board for the MP9473, a high-efficiency, step-down regulator with integrated power MOSFETs.
The MP9473 offers a very compact solution to achieve a 3.5A continuous output current over a wide input supply range with excellent load and line regulation. It also provides fast transient response and good stability fora wide input supply and load range.
The EV9473-L-00A is a fully assembled and tested evaluation board. It generates a 3.3V output voltage at load currents up to 3.5A from a 7V to 36V input range. The switching frequency is set at 500kHz.
