Renesas ZSPM8015

Beschreibung

The ZSPM8015-KIT Open-Loop Evaluation Board is designed to demonstrate the optimized small-size, highefficiency performance of the ZSPM9015 DrMOS multi-chip module. The board is a high density, high-efficiencydesign, with a 1 MHz operating frequency and peak efficiency of over 93% with a 1.0V VOUT condition. This board also demonstrates the ease of layout for printed circuit board artwork.

The board was designed as an open-loop control to have only common passive components in a synchronous buck converter without a PWM controller. The open-loop control method is more reliable and flexible, allowing performance testing with identical conditions. Since the ZSPM9015 pin map is industry standard, it is easy to compare its performance to other DrMOS devices without changing other components.

See Appendix B for the schematic for the Evaluation Board. See Appendix A for the Evaluation Board's physical specifications and layouts for the individual layers of the circuit board.
