SILANNA SEMICONDUCTOR INTRODUCES VERSATILE 12A BUCK CONVERTER FOR ULTRA-COMPACT PCB LAYOUT

Silanna Semiconductor, an innovative producer of disruptive technologies, today announced its highly integrated SZPL8216A family of synchronous point-of-load (PoL) buck converters. These DC/DC buck converters integrate the functions of the DC/DC constant-on-time (COT) controller, output gate drivers and output power blocks all in one compact 3mmx4mm QFN package to deliver the best power density with a minimum external component count. The devices enable designers to achieve ultra-compact PCB layout, high power density and high efficiency for low power loss in demanding and space-constrained applications such as enterprise servers, telecommunications, and networking equipment.

The SZPL8216A-A, SZPL8216A-B and SZPL8216A-C family of devices delivers up to 12 Amps with 94% peak efficiency when converting from a nominal 12 V input down to a 0.6 V to 5.5 V output voltage range. Providing design versatility, the devices feature a selectable switching frequency, 600 kHz to 1 MHz, allowing users to make design-specific decisions to optimize their component size versus efficiency. With the ability to operate at 1MHz, designers can use a smaller output filter to minimize their total PCB solution size.

Other features include programmable current limit and soft start time; remote output voltage sensing; pre-biased start-up and a full suite of robust power supply protection features including UVLO/OCP/OVP/UVP and OTP. Providing additional design versatility, the devices may operate from a single supply using their internal LDOs, or designers may bypass them and instead use an external 3.3 V or 5 V bias supply to increase conversion efficiency further.
