33702 MICROPROCESSOR POWER SUPPLY (3.0 A)
The 33702 is a monolithic IC providing an efficient means of obtaining power for
the Motorola Power QUICC I and II microprocessor families and other advanced
microprocessors. The IC incorporates a high-performance synchronous switching
regulator. The regulator is capable of delivering 3.0 A to power the microprocessor's
core and linear circuitry to control an external low-drop FET for powering the micro-
processor'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.
