Silanna Semiconductor Delivers Highest Power Efficiency and Greatest Power Density 65W USB-PD Charger Design at Reduced BoM Costs

SAN DIEGO, Dec. 3, 2020 /PRNewswire-PRWeb/ -- Silanna Semiconductor, The Power Density Leader, today announced a breakthrough 65W USB-PD reference design, achieving 30W/inch3 uncased power density and over 94% efficiency from an all-silicon design for a universal input AC/DC power adapter, utilizing their expanded portfolio of Active Clamp Flyback Controllers (ACF). Silanna Semiconductor focuses on the ultimate power management challenges with the best-in-class power density and efficiency that delight customers with unprecedented BoM savings. The full production release of the SZ1130 ACF PWM controller was announced in September and this new 65W USB-PD reference design demonstrates performance results utilizing all-silicon system design know-how.

The 65W USB-PD reference design, supporting 5V/3A, 9V/3A, 15V/3A and 20V/3.25A output voltages, targets a wide range of consumer power adapter applications. The technical sales team has been working directly with customers, demonstrating the advantages of Silanna Semiconductor's ACF controllers by delivering the best-in-class efficiency and the highest power density with reduced BoM costs from all-silicon designs.

"Customers are delighted to know that our 65W USB-PD reference design is capable of delivering higher performance in a smaller form factor for their design needs," said Ahsan Zaman, Director of Marketing. "The reference design demonstrates how well-suited the SZ1130 is for high efficiency and high power density AC/DC power adapters. SZ1130 is designed for up to 65W output power, including USB-PD and Quick Charge applications."

SZ1130 devices are ACF controllers that integrate an adaptive digital PWM controller and the following Ultra High-Voltage (UHV) components: an Active Clamp FET, Active Clamp Gate Driver, and a Startup Regulator. This unprecedented integration level facilitates designing efficient, high power density adapters with low BoM cost to satisfy power-hungry mobile phones, tablets, notebooks, and video game consoles.

The SZ1130 is fully supported by the Silanna Semiconductor's Asian Center of Excellence (ACE) design support center. All this, alongside the extensive AC/DC and DC/DC products are available at the demo room at https://www.powerdensity.com.

SZ1130-based AC/DC power supplies easily meet the stringent DoE and CoC efficiency and no-load standby power requirements.
