5 / 10 page High-Efficiency LCD Boost with True Shutdown _______________________________________________________________________________________ 5 PIN NAME FUNCTION FB (MAX8570/ MAX8571/ MAX8574) Feedback for setting the output voltage. Connect FB to the center of a resistor voltage-divider from the output to GND to set positive output voltages. 1 OUT (MAX8572/ MAX8573/ MAX8575) Output. The output voltage is preset to 15V. Connect a 1µF ceramic capacitor from OUT to GND. In shutdown, OUT is pulled to GND by an internal 7.5M Ω resistor. 2 GND Ground 3 SHDN Shutdown Input. A logic low at SHDN places the part in low-power shutdown mode. Pull SHDN high or connect to VCC for normal operation. 4LXInductor Switching Connection 5SW Isolation Switch Output. Internally connected to the drain of a p-channel MOSFET used to isolate the output from the input during shutdown. Connect a 4.7µF ceramic capacitor from SW to GND. If true shutdown is not required, SW can be left open with the input supply connected directly to the inductor. 6VCC Input Voltage Supply. Connect a 2.7V to 5.5V input supply to VCC. Connect a 1µF ceramic capacitor from VCC to GND.
