Standard Application
PT8139—12V
Description
The PT8139 Excalibur 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.
Features
Single Device: 30ADC
+12-V Input
Programmable Output Voltage:
1.7V to 4.0V via 5-Bit Code
Multiphase Topology
High Efficiency: 92% @3.3V
Output Remote Sense
30-A Programmable Integrated
Switching Regulator
SLTS156
(3/8/2002)
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.
