Overview
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.
For high-power requirements, the MAX8574 and MAX8575 use a 500mA current limit and supply up to 20mA at 20V.
The MAX8571 and MAX8573 use a 250mA current limit for a compromise between ripple and power.
Built-in safety features protect the int...
