age. The 10A capability allows easy integration of
the latest high-speed, low-voltage 碌Ps and bus
drivers into existing 5V systems.
The output voltage of the PT7600 is easily
programmed with a 5 bit input compatible with
Intel鈥檚 Pentium
廬
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.
1200碌F of output capacitance are required for
proper operation.

* ISR-will operate down to no load with reduced specifications. Please note that this product is not short-circuit protected.
** The minimum input voltage is 4.5V or V
out
+1.2V, whichever is greater.
*** See SOA curves.
Output Capacitors:
The PT7600 series requires a minimum output capacitance of 1200碌F for proper operation. Do not use Oscon type capacitors.The maximum allowable
output capacitance is 7,500碌F. 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 1碌H. 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.
