This application note describes the features and functions of V-Infinity's VPOL15A-5-SMT series of non-isolated dc-dc converters. These are highly efficient, reliable and compact, high power density, single output dc-dc converters. These "Point of Load" modules serve the needs specifically of the fixed and mobile telecommunications and computing market, employing economical distributed power architectures. The VPOL15A-5-SMT series provide precisely regulated output voltage range from 0.9V to 3.63Vdc over a wide range of input voltage (Vi=3.0 5.5Vdc) and can operate over an ambient temperature range of 40°C to +85°C. Ultra-high efficiency operation is achieved through the use of synchronous rectification and drive control techniques. The modules are fully protected against short circuit and overtemperature conditions. V-Infinity's world class automated manufacturing methods, together with an extensive testing and qualification program, ensure that all VPOL15A-5-SMT series converters are extremely reliable.
