Product Summary

The LM2622MM-ADJ is a step-up DC/DC converter with a 1.6A, 0.2Ω internal switch and pin selectable operating frequency. With the ability to convert 3.3V to multiple outputs of 8V, -8V, and 23V, the LM2622MM-ADJ is an ideal part for biasing TFT displays. The LM2622MM-ADJ 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 LM2622MM-ADJ is available in a low profile 8-lead MSOP package. The applications of the device include TFT Bias Supplies, Handheld Devices, Portable Applications, GSM/CDMA Phones and Digital Cameras.
