Product overview

Description

The STDES-200GANADP reference design is a 19 V-200 W 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.

The architecture is based on a two-stage approach: a front-end transition mode PFC preregulator and a downstream LLC resonant half bridge converter. The PFC and LLC controllers are integrated in the STCMB1 combo IC.

The SRK2001A control implements the synchronous rectification. The PFC section uses a proprietary and constant-on-time control methodology that does not require a sinusoidal input reference, reducing the system cost and external component count. The LLC section is based on a proprietary time shift control method. This improves dynamic behavior and input ripple rejection, resulting in a cleaner output voltage.

A higher efficiency is ensured thanks to the reduction of switching and conduction losses and to the elimination of reverse recovery loss thanks to the MASTERGAN application.

Users do not have to take care anymore of GaN driving complexity to enjoy the benefits of GaN technology, thanks to the highly integrated MASTERGAN1 IC, enhancing the robustness of the application and layout simplifications.
