Buck DC-DC Converter IC  
The TB7106F is a single-chip buck DC-DC converter IC that utilizing a  
chopper circuit. The TB7106F adopts bootstrap system and contains  
high-speed and low-on-resistance N-channel MOSFETs for the high side  
main switch to achieve high efficiency.

Because of an external phase compensation element, the optimal phase compensation according to the output  
filter capacitor can be realized.  
Allows the use of a small surface-mount ceramic capacitor as an output filter capacitor.  
Housed in a small surface-mount package (SOP Advance) with low thermal resistance.

This product has a MOS structure and is sensitive to electrostatic discharge. Handle with care.  
The product(s) in this document (“Product”) contain functions intended to protect the Product from temporary  
small overloads such as minor short-term overcurrent, or overheating. The protective functions do not necessarily  
protect Product under all circumstances. When incorporating Product into your system, please design the system  
to avoid such overloads upon the Product, and to shut down or otherwise relieve the Product of such overload  
conditions immediately upon occurrence. For details, please refer to the notes appearing below in this document
