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.
