Description: The PT7705 is a series of high-performance, 18 Amp Integrated Switching Regulators (ISRs) housed in a 27-pin SIP package. The 18A capability allows easy integration of the latest high-speed, low-voltage µPs and bus drivers into existing 5V systems.
The PT7705 series has been designed to work in parallel with one or more of the PT7749 - 18A current boosters for increased Iout in increments of 18A.
The output voltage of the PT7705 can be easily programmed from 1.3V to 3.5V with a 5 bit input compatible with Intel’s Pentium II Processor®. A differential remote sense is also provided which automatically compensates for any voltage drop from the ISR to the load.
1200µF of output capacitance are required for proper operation.
FEATURES:
- Single-Device: +5V Input
- 5-bit Programmable: 1.3V to 3.5V at 18A
- High Efficiency
- Input Voltage Range: 4.5V to 5.5V
- Differential Remote Sense
- 27-pin SIP Package
- Parallelable with PT7749 18A "Current Boosters"
