XYSemi XR4981A

SYNCHRONOUS BOOST CONTROLLER 2.8V~36V Input 5V~36V Output, Extended NMOS

Overview

Topology Boost Converter
Input voltage 2.8-36 V
Output 1 36 V
IC revision 0.2

Description

XR4981A is a high efficiency synchronous boost controller that converts from 2.8V~36V input range and up to 36Voutput voltage with two outside N-channel MOSFETs for the synchronous switches.The XR4981A 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 toobtain a high efficiency
