MAX8574 - High-Efficiency LCD Boost

Download the MAX8574 datasheet PDF. This datasheet also covers the MAX8570 variant, as both devices belong to the same high-efficiency lcd boost family and are provided as variant models within a single manufacturer datasheet.

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.

19-3329; Rev 3; 3/10 MAX8570–MAX8575 EVAALVUAAILTAIOBNLEKIT High-Efficiency LCD Boost with True Shutdown General 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 component count and a high switching frequency (up to 800kHz) allows for tiny surface-mount components. Three current-limit options are available. The MAX8570 and MAX8572 use a 110mA current limit to reduce ripple and component size in low-current applications.
