PCB layout
Make VIN and GND line sufficient. If their impedance is
high, noise pickup or unstable operation may result. Connect
capacitors C1 and C2 as close as possible to the IC, and make
wiring as short as possible.
Reverse Current Protection
The NCP4632 device include a Reverse Current
Protection Circuit, which stops a reverse current flowing
from the VOUT pin to the VIN or GND pin when the voltage
on VOUT becomes higher than VIN. The reverse current
protection circuitry switches the output power device of the
regulator off as soon as VIN drops to < 30 mV above VOUT.
In this state, reverse current is restricted to less than 10 m A,
which flows to ground. As VIN recovers, the power device
is switched back on. In order to avoid unstable behavior,
there is a 5 mV hysteresis incorporated in the design which
will require the dropout to rise above 35 mV before the
power device is switched on again. Therefore, the minimum
voltage dropout of the device at small output current is
limited to 35 mV. Figures 40 and 41 show the diagrams of
both operating modes.
