Freescale Semiconductor Technical Data Document Number: MC34703 Rev.

5.0, 8/2006 10A+ Switch-Mode Power Supply with LDO Regulator The 34703 integrated power supply IC is designed to support the PowerQUICC™ family of MCUs as well as other MCUs and DSPs requiring a high current core supply.

The 34703 incorporates a highperformance switching regulator for the microprocessor’s core supply, and a low-dropout (LDO) linear regulator control circuit to provide I/O and bus voltage.

The switching regul
