Detailed Descriptions
The NCP5810D 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-by-cycle peak
current limit and thermal provide value added features to
protect the device.
Boost Operation
The internal oscillator provides a 1.75 MHz clock signal
to trigger the PWM controller on each rising edge (SET
signal) which starts a cycle. During this phase the low side
MN1 switch is turned on thus increasing the current
through the inductor L1. The switch current is measured by
the SENSE CURRENT and added to the RAMP COMP
signal. Then PWM COMPP compares the output of the
adder and the signal from ERROR AMP. When the
comparator threshold is exceeded, the MN1 power switch
is turned off until the rising edge of the next clock cycle. In
