Upgrade to myMPS+Product Description
The EV4473-L-00A is an evaluation board for the MPQ4470, a high-efficiency step-down regulator with integrated power MOSFETs.
MPQ4470 offers a very compact solution to achieve a 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 for wide input-supply and load range.
The EV4473-L-00A is a fully assembled and tested evaluation board. It generates a +3.3V output voltage at load current up to 5A from an 4.5V to 36V input range. Switching frequency is set at 500kHz.
This evaluation board is available for both EV4473 and EVQ4473.

IC Details
The MPQ4473 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 MPQ4473 operates at high efficiency over a wide-output-current load range.
MPQ4473 has full protection features including, short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown (TSD).
The MPQ4473 requires minimal, readily available, standard, external components, and is available in a compact 3mmx4mm, 20-pin, QFN package.
