Description
The PT7681 Excalibur is a high
performance integrated switching regu-
lator (ISR), which is housed in a 27-pin
space-saving solderable copper pack-
age. Operating from a +5V input source,
the PT7681 delivers up to 30A of out-
put current over the adjustable output
voltage range of 2V to 3.5V. The high
output current and relatively small size
makes the PT7681 suitable for power-
ing high-end DSP, microprocessor,
and ASIC circuits requiring core or I/O
logic supply voltages as low as 2V. The
output voltage is programmable via a
4-bit input code.

Ordering Information
PT7681
= 2 to 3.5 Volts
A special feature of the PT7681 is
the Margin Up and Margin Down
controls. These controls provide a
convenient method for testing the
load circuit over its supply voltage
margins during production and quali-
fication test programs.
Other features include output short-
circuit and over-temperature protection,
a standby on/off control, and a differ-
ential remote sense to compensate for
voltage drop between the regulator and
load.
