XR2981
3.3V~5V Input 24W Output Step-up DC/DC Converter

 
GENERAL DESCRIPTION
The XR2981 is a high frequency, high efficiency DC to DC converter with an integrated 12A, 25mΩ power switch
capable of providing an output voltage up to 24V. The fixed 600KHz allows the use of small external inductions and capacitors and provides fast transient response. It integrates Soft start, Comp,only need few components outside.
It can output 6V 3.5A、 9V 2A when 3.3V Battery input and output 6V 4.5A、 9V 3A when 3.6V Battery input at good heat dissipation condition.
