Features

  • Single-Device: +5V input
  • 5-bit Programmable: 1.3V to 3.5V@10A
  • High Efficiency
  • Input Voltage Range: 4.5V to 5.5V
  • Differential Remote Sense
  • 27-pin SIP Package The PT7600 is a new series of high- performance, 10 Amp Integrated Switching Regulators (ISRs) housed in a 27-pin SIP pack- age. The 10A capability allows easy integration of the latest high-speed, low-voltage µPs and bus drivers into existing 5V systems. The output voltage of the PT7600 is easily programmed with a 5 bit input compatible with Intel’s Pentiumâ II Processor from 1.3V to 3.5V . 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.

Please note that this product is not short-circuit protected. The minimum input voltage is 4.5V or Vout+1.2V, whichever is greater. * See SOA curves. Output Capacitors: The PT7600 series requires a minimum output capacitance of 1200µF for proper operation. Do not use Oscon type capacitors.The m aximum allowable output capacitance is 7,500µF . See Capacitor Application Note. Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 10ADC with a typical value of 1µH. The input capacitance must be rated for a minimum of 1.0 Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
