PT7615—5V
20-A Low-Voltage Programmable
Integrated Switching Regulator
SLTS163
(Revised 12/13/2001)
Features
Single-Device: +5V Input
20A Output
5-bit Programmable:
1.075V to 1.85V (25mV Steps)
VRM 9.0 Compatible
High Efficiency (87%)
Description
The PT7615 power module is a 20-A
fully integrated switching regulator (ISR)
housed in a 27-pin aluminum SIP package.
Operating from a 5V-input bus, the
PT7615 produces a tightly regulated
supply voltage that is programmable over
the range, 1.075V to 1.85V. The output
voltage is selected via a 5-bit code. The
code adjusts the voltage in steps of 25mV
and is VRM 9.0 compatible.
This regulator is most suitable for
applications that employ microprocessor
and DSP products that require core supply
voltages as low as 1.075V.
The PT7615 includes a Shutdown
control, Differential Remote Sense, and
Short-Circuit Protection.
