概述：
The CP8335 is synchronous converters with an
input-voltage range of 6V to 30V. It has an integrated
low-side switching FET that eliminates the need for
an external diode which reduces component count.
Efficiency is maximized through the integrated
90-mΩ and 65-mΩ MOSFETs, low IQ and pulse
skipping at light loads. Using the enable pin, the
shutdown supply current is reduced to 2μA. This
step-down (buck) converter provides accurate
regulation for a variety of loads with a well regulated
voltage reference that is 1.5% over temperature.
Cycle-by-cycle current limiting on the high-side
MOSFET protects the CP8335 in overload situations
and is enhanced by a low-side sourcing current limit
which prevents current runaway. A low-side sinking
current-limit turns off the low-side MOSFET to
prevent excessive reverse current.
Hiccup protection is triggered if the overcurrent
condition continues for longer than the preset time.
Thermal shutdown disables the device when the die
temperature exceeds the threshold and enables the
device again after the built-in thermal hiccup time.
