1.4 Device Information
TPS568236 is the main device on the EVM board. The TPS568236 is a single, D-CAP3
synchronous buck converter requiring a very low external component count. Features include an accurate
reference voltage, fast load transient response, auto-skip mode operation for light load efficiency, FCCM light
load operation with > 25-kHz switching frequency, D-CAP3 control mode with good line, load regulation, and
does not require external compensation.
