32 SOICW
1.5 A Switch-Mode Power Supply
with Linear Regulator
The 33701 provides the means to efficiently supply the Power QUICC I,
II, and other families of Motorola microprocessors and DSPs. The 33701
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 m
N-channel power MOSFETs to provide protection features
and to allow space-efficient, compact design.
The 33701 incorporates many advanced features; e.g., precisely
maintained up/down power sequencing, ensuring the proper operation and
protection of the CPU and power system.
