Semtech offers a wide range of high performance DC-DC switching regulator ICs with both integrated and non-integrated switches and synchronous and non-synchronous voltage regulators. These buck and boost voltage regulators and converters operate from input voltages of 2.7V to 40V, with frequencies up to 4MHz, and high efficiency up to 96%.

Semtech switching regulators also include EcoSpeed® devices, which incorporate 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.
