Microprocessor Power Supply (3.0 A); \n?I2C with address register selection for programming control\n\n\n?Programmable internal Watchdog and Power-ON Reset to ensure MCU performance integrity\n\n\n?Synchronous buck converter with cycle-by-cycle PWM current mode control for enhanced output voltage accuracy\n\n\n?Boost converter for enhanced low-voltage performance\n\n\n?Adjustable switching regulator output voltage via external resistor divider\n\n\n?External RC programmed Reset Power-UP Delay timer\n\n\n;

Overview The 34702 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.\nThe 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 microprocessor's I/O operations. Both regulator output voltages are independently adjustable.\nA 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Seven +/-1.0% Output Voltage Margining steps are provided to facilitate easy system development.\nArchived content is no longer updated and is made available for historical reference only.\n
