Product Advantage:

>Dual output DC-DC converter is a tiny board. Input supply 36-72V DC.  It is monolithic integrated circuit specifically designed for fly back, step-up (boost), and forward converter applications. All products 100% aging test. We do accept custom order, you can send us details. With wide application in many fields, such as optical, communications, broadcast devices, etc.

>Actually, other features include soft start mode to reduce in-rush current during start up, current mode control for improved rejection of input voltage and output load transients and cycle-by-cycle current limiting. 

>Ideal for a wide variety of applications. A current limited, fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad range of load current. Operation with up to 100% duty cycle provides the lowest possible dropout voltage to extend useful battery life.

>With many years’ effort, we have attained full experiences and abilities in developing our product lines according to customer’s specifications. Your inquiry related to our products or prices will be replied in 24hours. Whatever your requirement we look forward to your contact, we will suggest a DC-DC converter that’s right for your application.
