DESCRIPTION

The XR2203 is a high frequency, high

efficiency DC to DC converter with an

integrated 2.8A, 0.1Ω power switch

capable of providing an output voltage up

to 26V. The fixed 1.2MHz allows the use

of small external inductions and

capacitors and provides fast transient

response. It integrates Soft start, Comp,.

only need few components outside.
