Product Details

ROHM’s 1.0A/1.5 MHz synchronous step-down switching regulator BD8312HFN produces step-down output including 1.2, 1.8, 3.3, or 5 V from 4 batteries, batteries such as Li2cell or Li3cell, etc. or a 5V/12V fixed power supply line. This IC allows easy production of small power supply by a wide range of external constants, and is equipped with an external coil/capacitor downsized by high frequency operation of 1.5 MHz, built-in synchronous rectification SW capable of withstanding 15 V, and flexible phase compensation system on board.

Input voltage range 3.5 to 14V 
Includes two power FET transistor (1.0A)
High speed frequency 1.5MHz .
Include gain phase compensation RC for error AMP.
Soft start circuit / Timer latched prevention circuit from shorting..
HSON8 package (2.9mm x 3mm, 0.65mm pitch ).
