NB650AGL-Z

The NB650A is fully-integrated, high-frequency, synchronous, rectified, step-down, switch-mode converters with dynamic-output–voltage control. It offers a very compact solution to achieve 6A of continuous output current over a wide input supply range, and has excellent load and line regulation. The NB650A operates at high efficiency over a wide output-current–load range. Constant-On-Time control mode provides fast transient response and eases loop stabilization. 2-bit VID inputs support changing the output voltage on-the-fly. Full protection features include short-circuit protection, over-current protection, over-voltage protection, under-voltage protection, and thermal shut down. The NB650A requires a minimal number of readily-available standard external components, and is available in a space-saving 3mm×4mm QFN17 package.
