MAXM17505高效DC-DC降压型电源模块

Maxim MAXM17505 High-Efficiency DC-DC Step-Down Power Modules integrates a number of devices in a low-profile, thermally efficient system-in-package (SiP). They combine a switching power supply controller, dual n-channel MOSFET power switches, fully-shielded inductor, and the compensation components all in a single package. Each of these devices operate over a wide input voltage range of 4.5V to 60V and delivers up to 1.7A continuous output current. This provides an excellent line and load regulation over an output voltage range of 0.9V to 12V. The device only requires five external components to complete the total power solution. The high level of integration significantly reduces design complexity, manufacturing risks, and offers a true plug-and-play power supply solution.
