STMicroelectronics STCMB1 | Demoboard STDES200GANADP

Beschreibung

The STDES-200GANADP reference design is a 19V-200W converter tailored for the typical specification of an AC-DC adapter for all-in-one systems, gaming applications, SMPS for LED TV, and lighting applications. It ensures a wide input main range, a very low power consumption at light load, and a good average efficiency.
