DESCRIPTION
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.
