GENERAL DESCRIPTION

The AMS6101 is an adjustable step-up DC/DC converter with a 2A internal switch. With the ability to set the output voltage up
to 23V, the AMS6101 is an ideal part for biasing TFT displays. The AMS6101 can be operated at switching frequencies of 600
kHz allowing for easy filtering and low noise. An external compensation pin gives the user flexibility in setting frequency
compensation, which makes possible the use of small, low ESR ceramic capacitors at the output. The AMS6101 is available in a
low profile 8-lead SOIC EDP (thermally enhanced) package.
