Description
The TPS5433xA family of devices are synchronous
converters with an input-voltage range of 4.5 V to 28
V. These devices include This device 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 128-
mΩ and 84-mΩ MOSFETs, low IQ and pulse skipping
at light loads. Using the enable pin, the shutdown
supply current is reduced to 2 μA. 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 TPS5433xA family of devices
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.
