STEVAL-ISA018V1

STEVAL-ISA018V1 demonstration board presents a high efficiency solution for industrial switched mode power supplies up to 150W continuous output power, with peak power of 240W. 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 of 24V with IO of 6 A and overload capability up to IO of 10A. 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.

• Input voltage range 185V to 265V ac
