MAX8573 Datasheet | Maxim Integrated

Description The MAX8570 family of LCD step-up converters uses an internal n-channel switch and an internal p-channel output isolation switch. These converters operate from a 2.7V to 5.5V supply voltage and deliver up to 28V at the output. A unique control scheme provides the highest efficiency over a wide range of load conditions. The internal MOSFET switch reduces external ponent count and a high switching frequency (up to 800k Hz) allows for tiny surface-mount ponents. Three current-limit options are available. The MAX8570 and MAX8572 use a 110m A current limit to reduce ripple and ponent size in low-current applications. For high-power requirements, the MAX8574 and MAX8575 use a 500m A current limit and supply up to 20m A at 20V. The MAX8571 and MAX8573 use a 250m A current limit for a promise between ripple and power. Built-in safety features protect the...
