Preliminary Information 3.0 A Switch-Mode Power Supply with Linear
Regulator
The 33702 provides the means to efficiently supply the Power QUICC™ I, II, and other families of Motorola microprocessors and DSPs. The 33702 incorporates a high-performance switching
regulator, providing the direct supply for the microprocessor’s core, and a low dropout (LDO) linear
regulator control circuit providing the microprocessor I/O and bus voltage. The switching
regulator is a high-efficiency synchronous buck
regulator with integrated 50 mΩ N-channel power MOSFETs to provide protection features and to allow space-efficient, compact design. The 33702 incorporates many advanced features; e.g., precisely maintained up/down power sequencing, ensuring the proper operation and protection of the CPU and power system. Features Operating Voltage: 2.8 V to 6.0 V High-Accuracy Output Voltages Fast Transient Response Switcher Output Current Up to 3.0 A Undervoltage Lockout Power Sequencing Programmable Watchdog Timer Voltage Margining via Bus Overcurrent Protection Reset with Programmable Power-ON Delay Enable Inputs I2C™
