NCP5810D
Dual 1 W Output AMOLED
Driver Supply
The NCP5810D 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
NCP5810D 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 1.75ꢀMHz 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
NCP5810D is housed in low profile space-efficient 3x3 mm UDFN
package.
