Active-clamp flyback PWM controllers enable high-efficiency supply designs
Silanna Semiconductor announced the launch of an expanded portfolio of Active Clamp Flyback Controllers (ACF). The SZ1110 and SZ1130 devices are active clamp flyback PWM 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 level […]
Synchronous PoL buck converters sit in ultra-small footprint
Silanna Semiconductor 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 […]
Flyback PWM controller delivers 93% power efficiency
Silanna Semiconductor expanded its line of fully integrated active clamp flyback (ACF) controllers with the 60W SZ1105 flyback PWM controller. Like its 30W SZ1101 sibling, Silanna’s SZ1105 60W controller combines four key ACF components: an advanced adaptive digital ACF controller and three ultra-high-voltage (UHV) components – an active clamp MOSFET, an active clamp FET driver, […]
