NCP5810  
Dual 1 W Output AMOLED  
Driver Supply  
The NCP5810 is a dual−output DC/DC converter which can  
generate both a positive and a negative voltage. Both PWM  
converters achieve high efficiency for portable application. Thanks  
to the high output voltage accuracy and signal integrity the NCP5810  
is particularly suitable for powering applications such as AMOLED  
display drivers. The output voltage of the inverter is fully  
configurable using external feedback resistors, where the output  
voltage of the boost is internally fixed. The switching regulator  
operates at 1.75 MHz which allows the use of small inductors and  
ceramic capacitors. In addition both converters are internally  
compensated which simplifies the design and reduces the PCB  
component count. Cycle−by−cycle peak current limit and thermal  
shut down provide value added features to protect the device. The  
NCP5810 is housed in a low profile space efficient 3 x 3 x 0.55 mm  
LLGA package.
