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. Features Reduces Design Complexity, Manufacturing Risks, and Time-to-Market Integrated Switching Power Supply Controller and Dual-MOSFET Power Switches Integrated Inductor Integrated Compensation Components Integrated Thermal-Fault Protection Integrated Peak Current Limit Saves Board Space in Space-Constrained Applications Complete Integrated Step-Down Power Supply in a Single Package Small Profile 9mm x 15mm x 2.8mm SiP Package Simplified PCB Design with Minimal External BOM Components Offers Flexibility for Power-Design Optimization Wide Input Voltage Range from 4.5V to 60V Output-Voltage Adjustable Range from 0.9V to 12V Adjustable Frequency with External Frequency Synchronization (100kHz to 1.8MHz) Soft-Start Programmable Autoswitch PWM, PFM, or DCM Current-Mode Control Optional Programmable EN/UVLO Applications Distributed Supply Regulation FPGA and DSP Point-of-Load Regulator HVAC and Building Control Industrial Power Supplies Typical Application Circuit
