General Description
The LM2622 is a step-up DC/DC converter with a 1.6A, 0.2
internal switch and pin selectable operating
frequency. With the ability to convert 3.3V to multiple outputs of 8V, -8V, and 23V, the LM2622 is an ideal
part for biasing TFT displays. The LM2622 can be operated at switching frequencies of 600kHz and 1.3MHz
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 LM2622 is available in a low profile 8-lead MSOP package.
