Silanna Semiconductor Extends Power Of Highest Efficiency, Highest Power Density DC/DC Converter Family To 100W

Latest addition to the CO2 Smart Power™ DC/DC product family delivers industry-leading efficiency

San Diego, CA (PRWEB) - Silanna Semiconductor, The Power Density Leader, has extended its CO2 Smart Power™ family of wide-voltage, high-frequency point of load converters with a 100W device targeting USB-PD applications designed to deliver industry-leading efficiency.

Silanna Semiconductor focuses on ultimate power management challenges with devices that combine best-in-class power density and efficiency performance with unprecedented BoM savings. Operating at a switching speed of 667kHz, the SZDL3105B fully-integrated DC/DC converter (buck regulator) can supply up to 5 amps and 100 watts of output power.  It accommodates industry-leading wide input and output ranges that support up to 27VDC input and is supplied in a tiny 4mm x 4mm QFN package. 

Tim Wilhelm, Director of Marketing, explained, “Higher switching frequency means a smaller, lower cost, higher performing output filter that has delighted the clients we have sampled. The SZDPL3105B device enables ground-breaking efficiencies in the smallest size and weight designs. Our support tools give customers the flexibility and confidence to quickly increase the performance efficiency. This ultimately increases power density with volumes approaching 12% of that required by low-frequency competitive solutions. The SZDL3105 significantly reduces BOM cost, design cycles and time to market.” 

The SZDL3105B has unique features that optimize its performance in USB port power supply applications. Extremely low operating power dissipation enables the very low no-load power that is an important specification for regulatory certification. Internal and external feedback resistor divider flexibility supports custom design, while a momentary internal feedback path allows for clean and well-controlled start-up operation until external USB port controllers can bias themselves and smoothly take over control of the output voltage. 

“At Silanna Semiconductor we have the mantra ‘Power Management Re-Imagined’ and the SZDL3105B is one more example of how we approach the challenges of size and cost completely differently than our competitors,” said Mark Drucker, CEO of Silanna Semiconductor. “Our design team increased the operating frequency and maintained the highest efficiency and power density, which allows unheard of size and cost reductions. We are witnessing some fantastic customer reactions, which have resulted in a large number of early design wins particularly in USB-PD applications. We are building a stable of CO2 Smart Power devices and it's exciting to see our design teams focus on the end-to-end power solutions with complementary DC/DC and AC/DC product families that achieve best-in-class efficiency.”
