DESCRIPTION
The MP1471A is a high-frequency, synchronous, rectified, step-down, switch-mode converter with inter
nal power MOSFETs. It offers a very compact solution to achieve a 3A output current over a wide input supply range, with excellent load and line regulation. The MP1471A has synchronous-mode operation for FEATURES
• Wide 4.5V-to-16V Operating Input Range • 110m Ω/57m Ω Low-R DS(ON) Internal Power
MOSFETs • Proprietary Switching-Loss–Reduction
Technology
• High-Efficiency Synchronous-Mode
