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...
