Product Description

The EVQ4470-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 EVQ4470-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.

IC Details

The MPQ4470/4470A is a fully-integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. It 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 MPQ4470/4470A operates at high efficiency over a wide output current load range. 
MPQ4470 has full protection features include SCP, OCP, OVP latch, UVP, and thermal shutdown. MPQ4470A has the same protection features to MPQ4470 except has no OVP latch function.
The MPQ4470/4470A requires a minimal number of readily-available, standard, external components, and is available in a space-saving 3mm×4mm, 20-pin, QFN package.
