STEVAL-ISA018V1 demonstration board based on resonant
half-bridge SMPS for industrial applications
Introduction
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, V_O=24 V with I_O=6 A, and an overload capability
of up to I_O=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.
The board, shown in Figure 1, is obtainable using the order code STEVAL-ISA018V1.
