... OPAMP AGND AGND Detailed Descriptions The NCP5810 is a dual−output DC/DC converter which can generate both a positive and a negative voltage. The output voltage of the inverter is fully configurable using external feedback resistors. The switching regulator operates at 1.75 MHz which allows the use of small inductors and ceramic capacitors. The both converters are internally compensated which simplifies the design and reduces the PCB component count. Cycle− ...

... Three different electrical parameters need to be considered when selecting an inductor, the absolute value of the inductor, the saturation current and the DCR. During normal operation, the NCP5810 is intended to operate in Continuous Conduction Mode (CCM). The two equations below can be used to calculate the peak current for each ...
