Micropower management unit provides three isolated rails
The ADP1031 is a high performance, isolated micropower management unit (PMU) that combines an isolated flyback dc-to-dc regulator, an inverting dc-to-dc regulator, and a buck dc-to-dc regulator, providing three isolated power rails. Additionally, the ADP1031 contains four, high speed, serial peripheral interface (SPI) isolation channels and three general-purpose isolators for channel-to-channel applications where low power […]
Rad-tolerant PWM controller/GaN FET driver first to come in a plastic package
Renesas Electronics Corporation announced the space industry’s first plastic-packaged, radiation-tolerant PWM controller and Gallium Nitride (GaN) FET driver for DC/DC power supplies in small satellites (smallsats) and launch vehicles. The ISL71043M single-ended current mode PWM controller and ISL71040M low-side GaN FET driver are ideal for isolated flyback and half-bridge power stages, and motor control driver […]
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, […]
