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

Datasheet Summary

Description

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.

Features

  • n n n n n Operating voltage range of 2.7V to 7V 615kHz/1.25MHz pin selectable frequency operation Over temperature protection Optional soft-start function 8-Lead MSOP package.

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 ideal for driving high current white LEDs for flash applications. The LM3224 can be operated at switching frequencies of 615kHz and 1.25MHz allowing for easy filtering and low noise.
