Analog Devices / Maxim Integrated MAXM17546 DC-DC Step-Down Power Module
Analog Devices MAXM17546 DC-DC Step-Down Power Module combines a switching power supply controller, MOSFET power switches, shielded inductor, and the compensation components in a low-profile, thermally-efficient package. The device operates over a wide input voltage range of 4.5V to 42V. The MAXM17546 delivers up to 5A continuous output current with excellent line and load regulation over an output voltage range of 0.9V to 12V. The high level of integration significantly reduces design complexity and manufacturing risks and offers a true plug-and-play power supply solution, reducing time-to-market. The Analog Devices MAXM17546 can be operated in pulse-width modulation (PWM), pulse frequency modulation (PFM), or discontinuous conduction mode (DCM) control schemes.
