NB650A
High-Effeciency, Fast-Transient, 6A, 28V
Synchronous Step-Down Converters with 2-Bit VID
DESCRIPTION
The NB650A is fully-integrated, high-frequency,
synchronous, rectified, step-down, switch-mode
converters with dynamic-outputvoltage 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-currentload
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.
