GENERAL
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.
