EcoSpeed® DC-DC Converters

EcoSpeed® DC-DC Converters

The EcoSpeed® converter platform incorporates Semtech’s advanced, patented adaptive on-time (AOT) control architecture to deliver ultra-fast transient response and very high efficiency across light to full-power loads. This unique architecture offers the benefits of conventional converter topologies with optimal tradeoffs for best-in-class performance in next-generation low-power, dynamic point-of-load (POL) applications.

EcoSpeed DC-DC converters help designers meet today’s demanding "green" power requirements by efficiently managing both standby and full-current demands.
