Description
The PT8139 Excalibur鈩?module
is a high performance integrated
switching regulator (ISR), housed in
a solderable, 31-pin space-saving
copper package. Operating from an
input voltage of +12V, the module
provides up to 30A of power over a
range of low-output voltages.
The PT8139 incorporates a state-
of-the-art 2-phase multiple power
path. This topology extends the
output current range while improving
both the transient response and input
current ripple.
The PT8139 output voltage is
programmable over the voltage
range, 1.7V to 4.0V, via a 5-bit input
code. This makes the PT8139 an
ideal power source for many highly
integrated digital systems that de-
mand a high power supply current
at low voltages.
The PT8139 features include
short-circuit protection, thermal
shutdown, a Standby (On/Off)
control, and a remote sense to com-
pensate for voltage drop between
the regulator and the load.
