PMIC enables 10X Smaller Inductor plus 5X Bandwidth

SiBreeze Technologies, a developer of leading-edge proprietary technologies and IC products for power management applications, today announced the release of its ground breaking product the Si117 power management IC (PMIC) featuring SLIM SWITCHER ™ and BEST SWITCHER ™ technologies.

"When we introduced our SLIM SWITCHER ™ and BEST SWITCHER ™ technologies, we received tremendous interest. Now with the release of our Si117 product, one can validate our ground breaking technologies," said Sridhar Kotikalapoodi, Founder and Chief Executive Officer of SiBreeze Technologies.

Highlights of the technology include:

• 10X smaller inductor value than other industry leading solutions running at the same switching frequency - Turbo Fast Response and Slimmer Devices
• Better than 4 phase response, efficiency and noise with a single inductor - Ultra Small Volume, Multiple Independent CPU Voltage Rails and Reduced Bill of Materials.
• 5X bandwidth at same switching frequency - Efficient Dynamic Power-on-Demand for Increased Battery Life.
• 10X smaller inductor DCR - Significantly Decreased Inductor Temperature Rise and 3X Inductor Current Capability for a given volume

"Our technologies are beneficial to a wide range of applications ranging from reducing energy wastage in Data Centers to enabling slimmer form factor devices with increased battery run time in mobile and Internet of Things (IoT) applications," said Kotikalapoodi.

"Inductor size and value has been a big limiting factor in power supplies, limiting power supply speed and form factor.  Even in mobile devices, many power supplies are now being implemented with more expensive multi-phase power supplies each requiring multiple large inductors," Kotikalapoodi explained.

Features of the Si117 include:

• 5V to 14V input voltage switching regulator IC for mobile battery charging applications with 24V hold-off
• 10x smaller inductor value at the same switching frequency than existing solutions
• 10x smaller inductor CDR - 3x charge current capability for the inductor
• Increased voltage headroom with 10x smaller inductor DCR allows increased faster charge currents even with 5V standard charger input
• 5x faster response at a given switching frequency - ultra-fast transient response for dynamic system loads
• Instant charge - real, safe fast charge with decreased thermals, while other solutions are severely thermal limited by inductor DCR.

"Even with this increased cost and size, battery life, thermals and power supply speed still remain a major concern. Some high end applications in networking, Point of Load converters etc. utilize super expensive complex control algorithms providing incremental speed benefits," Kotikalapoodi added,

"With our 10X smaller inductor and DCR values. SiBreeze Technologies brings 5X the bandwidth, 3X Inductor current capability than that of high end applications to even most cost sensitive consumer applications," Kotikalapoodi noted, "It's the ultimate power experience for the end user."

Coming next from SiBreeze will be the Si347 mobile CUP power supply IC featuring:

• 10x smaller inductor and DCR values
• 3x inductor current capability for a given volume
• 5x faster response at a given switching frequency - ultra-fasts transient response for dynamic system loads, and demand tracking power supply
• Better bandwidth, current capability and noise with a single inductor than a 4-inductor, 4-phased loop
• Increased battery run time, slimmer components, and decreased thermals.
