High-Performance DC/DC Switching Regulators for Efficient Power Conversion
Semtech DC/DC regulators enable the use of smaller external components, minimizing overall solution size while providing superior reliability
Semtech DC/DC switching regulators deliver exceptional performance in compact packages, making them ideal for space-constrained applications where efficiency is critical. The buck (step down) regulators provide ultra-fast transient response while maintaining high efficiency across all load conditions from light to full power loads. These converters seamlessly transition into power save mode under light loads, significantly reducing power consumption without compromising performance.
The boost (step up) regulators complement this lineup with high efficiency and low noise operation, enabling applications that require a higher output voltage than the input source can provide. Both regulator types support a wide range of input voltages and programmable output options, making them suitable for diverse applications from portable devices to industrial equipment.
With high switching frequencies up to 4 MHz, Semtech DC/DC regulators enable the use of smaller external components, minimizing overall solution size while providing superior regulation and reliability. Whether users need to step down or step up voltage, Semtech offers a comprehensive portfolio of switching regulators to meet their power conversion needs.
