NB650/NB650H  
High-Effeciency, Fast-Transient, 6A, 28V  
Synchronous Step-Down Converters with 2-Bit VID  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The NB650/NB650H 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 NB650/NB650H  
operates at high efficiency over a wide output-  
current–load range.

•
Wide 4.5V-to-28V Operating Input Range  
6A Output Current  
Internal 50mΩ High-Side, 18mΩ Low-Side  
Power MOSFETs  
Proprietary Switching Loss Reduction  
Technique  
1% Reference Voltage  
Programmable Soft-Start Time  
2-bit VID Input  
Soft Shutdown  
Frequency Programmable from 150kHz to  
1MHz  
SCP, OCP, OVP, UVP, and Thermal  
Shutdown

•
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.  
Optional OCP Protection: Latch-Off Mode  
(NB650) and Hiccup Mode (NB650H)  
Output Adjustable from 0.6V to 13V  
Available in QFN17 (3mm×4mm) Package
