DESCRIPTION
The MPQ4480 is a high-frequency,
synchronous rectified, step-down, switch-mode
converter. It achieves 6A output current over a
wide input-supply range with excellent load and
line regulation over a wide input supply range.
The MPQ4480 has synchronous mode
operation for higher efficiency over the output
load range.
Fault condition protection includes hiccup
current limiting, OVP, and thermal shutdown
(TSD).
The MPQ4480 requires a minimal number of
readily available, standard external components.
The MPQ4480 is available in a QFN-25
(4mmx5mm) package.
