STEVAL-ISA018V1: 150W, 24V @ 6A, 85 ~ 185/185 ~ 265VAC

Summary

This user manual describes a high efficiency solution for industrial power supplies with a continuous output power of 150 W and peak power up to 240 W. It takes advantage of the resonant approach to minimize switching losses, resulting in higher than 90% efficiency. The topology is based on half-bridge and operated in a resonant fashion by means of a resonant LC tank, driven by the L6599 dedicated controller.

The board provides one regulated output, VO=24 V with IO=6 A, and an overload capability of up to IO=10 A. Output voltage and current are controlled by the TSM1011 constant voltage and constant current controller, providing square output regulation, while the overload is managed by thermal protection (PTC) on the output rectifiers.

Compliant with standards:

– EN60950 for safety
– EN55014 for EMI
