DESCRIPTION
The EVM3650-QW-00A is an evaluation board designed to demonstrate the capabilities of the MPM3650, a fully integrated, high-frequency, synchronous, rectified, step-down power module with an internal inductor. It offers an ultra- compact solution that achieves up to 6A of continuous output current across a wide 2.75V to 17V input voltage range, with excellent load and line regulation. Synchronous mode provides high efficiency across the output current load range. Constant-on-time (COT) control provides very fast transient response, easy loop design, and tight output regulation. Full protection features include short-circuit protection (SCP), over- current protection (OCP), under-voltage protection (UVP), and thermal shutdown. ELECTRICAL SPECIFICATIONS Parameter Symbol Value Units Input voltage V IN 2.75 to 17 V Output voltage V OUT 1 V Output current I OUT 6 A
