LM3224 Datasheet (Texas Instruments) - 615kHz/1.25MHz Step-up PWM DC/DC Converter

LM3224, 615kHz/1.25MHz Step-up PWM DC/DC Converter

The LM3224 is a step-up DC/DC converter with a 0.15Ω (typ.), 2.45A (typ.) internal switch and pin selectable operating frequency.

With the ability to convert 3.3V to multiple outputs of 8V, -8V, and 23V, the LM3224 is an ideal part for biasing TFT displays.

With the high current switch it is also id
