MAXM17546 4.5V to 42V, 5A High-Efficiency, DC-DC Step-Down Power Module with Integrated Inductor General Description Benefits and Features The Himalaya series of voltage regulator ICs and power Reduces Design Complexity, Manufacturing Risks, modules enable cooler, smaller and simpler power supply and Time-to-Market solutions. The MAXM17546 is an easy-to-use, step-down Integrated Synchronous Step-Down DC-DC power module that combines a switching power supply Converter controller, dual n-channel MOSFET power switches, fully Integrated Inductor shielded inductor, and the compensation components in Integrated FETs a low-profile, thermally-efficient system-in-package (SiP). Integrated Compensation Components The device operates over a wide input voltage range Saves Board Space in Space-Constrained of 4.5V to 42V and delivers up to 5A continuous output Applications current with excellent line and load regulation over an Complete Integrated Step-Down Power Supply in a output-voltage range of 0.9V to 12V. The high level of Single Package integration significantly reduces design complexity, manu- Small Profile 9mm x 15mm x 4.32mm SiP Package facturing risks, and offers a true plug-and-play power Simplified PCB Design with Minimal External BOM supply solution, reducing time-to-market. Components The device can be operated in the pulse-width modulation Offers Flexibility for Power-Design Optimization (PWM), pulse-frequency modulation (PFM), or discontinu- Wide Input-Voltage Range from 4.5V to 42V ous conduction mode (DCM) control schemes. Output-Voltage Adjustable Range from 0.9V to 12V The MAXM17546 is available in a low-profile, highly Adjustable Frequency with External Frequency thermal-emissive, compact, 29-pin, 9mm x 15mm x Synchronization (100kHz to 2.2MHz) 4.32mm SiP package that reduces power dissipation in PWM, PFM, or DCM Current-Mode Control the package and enhances efficiency. The package is Programmable Soft-Start easily soldered onto a printed circuit board and suitable Auxiliary Bootstrap LDO for Improved Efficiency for automated circuit board assembly.
