The 34701 is a monolithic IC providing an efficient means of obtaining power for the NXP® Semiconductors PowerQUICC®™ I and II microprocessor families and other advanced microprocessors.
The IC incorporates a high-performance synchronous switching regulator. The regulator is capable of delivering 1.5 A to power the microprocessor's core and linear circuitry to control an external low-drop FET for powering the microprocessor's I/O operations. Both regulator output voltages are independently adjustable.
A boost converter allows high-accuracy output voltages to be developed from source operating voltages as low as 2.8 V. Seven +/-1.0% Output Voltage Margining steps are provided to facilitate easy system development.
