Adopt back-to-back metal-oxide-semiconductor Q1 to replace Schottky diode to provide reverse input protection function, thus decrease voltage drop and power loss, shut down pin for one and be responsible for, between down period, quiescent current is decreased to 7 below μ A.
The application of carrying out surge protection and peak restrained technology, achieves Fang anti-Jie ﹑ carrying out surge protection and spike absorbs.Product can bear surge voltage 100V, duration 500mS; Peaking voltage 250V, duration 50uS.
3. buck topology circuit:
In order to provide high-precision output voltage under broad input voltage range, must manage with suitable control method driving switch mos, this circuit adopts series connection control mode, and the break-make of U2 control mos pipe Q5 completes decompression transformation, has overcurrent protection function.
4. boost topology circuit:
Adopt Boost topology technology, further increase the conversion efficiency of product, this circuit conversion efficiency can reach 92% ~ 95%.
A kind of power supply with Anti-surging function of the utility model, be a common technology, owing to have employed SMT and eutectic Welding technology, the Ti Ji ﹑ efficiently solving product dispels the heat and weight issue, can be used for other field, as in the adverse circumstances such as panzer, aircraft.At present, the problems such as the interference of the industry such as panzer, aircraft ubiquity and wide input voltage range work, use Anti-surging power module effectively can solve the problems such as antisurge interference and wide input voltage range work, therefore, along with this project technology transplant and apply, work to the electronic equipment such as vehicle-mounted, airborne reliably, raise labour productivity and bring good society, economy and ecological benefits.
