General Description

XR4981 is a high efficiency synchronous boost controller that converts from 3V ~36V input range and up to 36V output voltage with an outside N-channel MOSFET for the synchronous switch.

The XR4981 includes adjustable current limit, adjustable soft-start, adjustable compensation net and thermal shutdown preventing damage in the event of an output overload.

For different application we can select suitable compensation net、current limit、 soft start and select suitable MOSFET to obtain a high efficiency。
