Nano-quiescent, high-efficiency step-down converters save energy and space in IoT services
STMicroelectronics’ ST1PS01 step-down converters are engineered for small size, low quiescent current, and high efficiency at all values of load current, to save energy and real-estate in keep-alive point-of-load supplies and IoT devices such as asset trackers, wearables, smart sensors, and smart meters. Leveraging synchronous rectification, efficiency is 92% at 400mA full load and 95% when delivering […]
DC-DC converters optimized for high-volume wireless/microwave apps
Flex Power Modules is introducing the PKU4611A and PKU4617A, two new isolated DC-DC converters in the sixteenth-brick form factor. The new converters are ideal for low-power radio frequency power amplifier (RFPA) requirements within small cell radios and microwave applications. They offer a wide output trim range, which is optimized for the needs of low-power radio […]
