STEVAL-ISA018V1
Description
The STEVAL-ISA018V1 demonstration board presents a high efficiency solution for industrial switched-mode power supplies (SMPS) up to 150 W continuous output power, with peak power of 240 W. The design takes advantage of a resonant approach to minimize switching losses, resulting in efficiency higher than 90%.
The design is based on a half-bridge topology operated in a resonant manner by means of a resonant LC tank, driven by a dedicated L6599 high-voltage resonant controller.
The board provides one regulated output,
VO = 24 V with IO = 6 A and overload capability up to IO = 10 A.
Output voltage and current are controlled by a secondary-side IC (TSM1011), which provides square output regulation, while the overload is managed by thermal protection (PTC) on the output rectifiers.
