DESCRIPTION
The PT7761 is a high performance integrated switching regulator (ISR), housed in a solderable, 31-pin space- saving copper package. Operating from and input voltage of +5V, the PT7761 rovides up to 40A
of low- voltage power for the industry’s latest DSPs,and u-Processors.
The PT7761 performance extends both the flexibility and output current range of the "Big Hammer" series of Plug-in Power modules, and provides a state-of-the-art solution for highly integrated digital
systems that demand high power supply currents at low output voltages.
The PT7761 is programmable from 1.3V to 3.5V via a 5-bit input, which is compatible with Intel’s Pentium series microprocessors.
The PT7761’s features include a momentary-interrupt style of short-circuit protection, a standby control, and a differential remote sense to compensate for voltage drop between the ISR and load. For
additional output current the PT7761 can operate with up to three current boosters.
