Switching Regulator (Controller Type)
BD9763FVM
No.09028EAT07
●Description
BD9763FVM is a 1-channel high efficiency step-up switching regulator.
It is possible to choose small application space due to its high-speed operation (Max switching frequency 1.2MHz)
●Features
1) Build-in under voltage lock out circuit.
2) High accuracy reference voltage (2.5V±1.0%)
3) Establish maximum duty cycle internally.
4) CTL/SS terminal for both stand-by and soft-start function. (Soft-start time can be set by external capacitor)
5) MSOP8 thin and small package.
●Applications
Single-lens reflex cameras, digital video cameras, liquid crystal modules, DVD drive.
●Absolute Maximum Ratings(Ta=25℃)
