Founded in 2014 and based in Irvine, CA, TransSiP’s patent estate represents a portfolio of innovation in the application of advanced materials and 3D heterogeneous (active and passive) embedded system-in-package technologies to the challenge of More-than-Moore (MtM) electronic systems.
In the power conversion space, TransSiP’s lead product JC-PFM™ is a synchronous step-down micro DC-DC converter packaged in a 3D heterogenous SiP integrating switching controller, inductor, and TransSiP’s patent-pending JC™ switching noise jitter (“SNJ”) conditioning technology.
JC™ SNJ conditioning addresses the critical problem of chaotic noise present on the regulated output voltage of pulse-frequency modulation (PFM) type switching-mode DC-DC converters. JC™ does this through recognition and reduction of the uncertainty responsible for variation in timing of events in the negative feedback control loops used to trigger the semiconductor switches in the device.
Despite conversion efficiencies ranging from 80 - 95% depending on load conditions, up to now the problem of chaotic noise and variable switching frequencies has excluded PFM DC-DC converters from use with applications sensitive to supply bias noise such as spread-spectrum wireless communications and navigation/positioning. As a result, all battery-powered devices with communication and/or positioning functionality use linear DC voltage regulation (so-called “low dropout” or “LDO”). Linear regulators don’t output switching noise on the supply bias, but operate at much lower (<5 - 60%) efficiencies. Therefore despite advances in low-power semiconductor technologies, the voltage conversion necessary to supply a stable supply bias is stuck with the same old wasteful paradigm. In addition to the limitations on autonomy, the response by LDO regulators to variable load profiles (sleep <=> full load) introduced in attempts to maximize battery life introduces transients which can impact downstream circuitry or generate errors in analog to digital data convolution. These are effectively suppressed using TransSiP’s JC™ technology in the form of their Harmony™ SNJ conditioning module.
The Bottom Line
Whether a highly efficient, integrated JC-PFM™ solution or Harmony™ conditioning of an LDO, the result is a noise-optimized supply bias for powering wireless SoCs, RF components, high precision TCXOs, ADCs and other noise sensitive RF and analog circuit elements.
Field tests using JC-PFM™ to power one of the leading sports/runner platforms have not only shown as much as a 5X increase in battery life, but have conclusively demonstrated that TransSiP’s JC™ technology provides the ability to “Run Farther, Run Better”!
