MAXREFDES1032
Reference Guide
描述
The MAX17506 is a high-efficiency switching regulator that delivers up to 5A load current at output voltages from 0.9V to (0.9 x VIN). The device integrates the highside MOSFET and operates over 4.5V to 60V, making it ideal for on-board point-of load and post-regulation applications.
The device features a peak current-mode control architecture. Built-in compensation across the output voltage range eliminates the need for external compensation components. The feedback regulation accuracy over -40°C to +125°C is ±1.4%.
Output overload hiccup protection and cycle-by-cycle peak-current limit provide for ultra-safe operation in short-circuit conditions.
In this document a step-down DC-DC converter using the MAX17506 is demonstrated for a 12V output application. The power supply delivers up to 5A at 12V.
