TransSiP's ground-breaking JC-PFM™ DC-DC converter system-in-package (SiP) uses TransSiP's patent-pending jitter conditioning technology to eliminate chaotic noise normally produced by pulse-frequency modulated DC-DC power conversion. For the first time, this breakthrough enables use of efficient, PFM DC-DC power conversion in highly noise-sensitive applications such as spread-spectrum communications (WiFi, BLE, ZigBee) and GPS/GNSS navigation receivers, bringing advances in battery life, transceiver range, and overall system performance to portable, wearable, IoT, and other power-constrained applications.
