High-Efficiency DC-DC Converter Fits LDO Footprint
Switching regulators can replace LDOs for generating 1.5V/3A output from a 3.3V input. Board space in existing LDO designs is typically limited, often too small for a switching regulator. This application note discusses the MAX8505, a switching regulator with MOSFETs packaged in a 16-pin QSOP that fits an LDO footprint.
