Renesas' plastic-packaged, radiation tolerant PWM controllers are used for DC/DC power supplies in small satellites (smallsats) and launch vehicles. These controllers provide fast signal propagation and output switching in a small plastic package, reducing PCB area up to 3x compared to competitive ceramic packages. It reduces power loss more than 3x, and its adjustable operating frequency enables higher efficiency and the use of smaller passive filter components.
