PT7700

• Single-Device: +5V input
• 4-bit Programmable:
   2V to 3.5V@15A or
   1.3V to 2V @ 15A output
• High Efficiency
• Input Voltage Range:
   4.5V to 5.5V
• Differential Remote Sense
• 27-pin SIP Package:
   V = 1.0"(H) x 3"(L) x 0.55"(W) 
   H = 0.55"(H) x 3"(L) x 1.5"(W)
• Parallelable with PT7749
  15A "Current Boosters"

The PT7700 is a new series of highperformance, 15 Amp Integrated Switching Regulators (ISRs) housed in a 27-pin SIP package. The 15A capability allows easy integration of the latest high-speed, lowvoltage µPs and bus drivers into existing 5V systems.

The PT7700 series has been designed to work in parallel with one or more of the PT7749 - 15A current boosters for increased Iout in increments of 15A.

Two products are offered in the series with different output voltage ranges that are easily programmed with a 4 bit input compatible with Intel's PentiumProcessor. A differential remote sense is also provided which automatically compensates for any voltage drop from the ISR to the load.

An input filter and 1200µF of output capacitance are required for proper operation.
