HT7466 -- 3A Step-Down DC to DC Converter General Description
The HT7466 is a DC-DC buck regulator. The
builtin high driver NMOS provides a monolithic solution
for high efficiency step-down DC-DC converter. With 3A output
current, the wide input voltage range and stable output voltage
regulation can widely use in all kinds of application, like
communication, power for high power LED, battery charger, etc. The
protection function include over current and over temperature
protection. The soft start function prevent inrush supply current
and output overshoot when initial startup. The under voltage lockout
is set to 4.1V. It prevents abnormal situation occurring.
The HT7466 requires a minimum number of
standard external components and is available in a 8-pin SOP package
for small area PCB application.
