LM2622 Datasheet (National Semiconductor) - Step-up PWM DC/DC Converter

LM2622, Step-up PWM DC/DC Converter

The LM2622 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 LM2622 is an ideal part for biasing TFT displays.

The LM2622 can be operated at switching frequencies of 600
