**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 high performance 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 regulator is an efficient synchronous buck converter with
integrated low RDS(ON) high side and low side FETs. Temperature and current
sensing is built in and provides protection for the IC as well as the external
circuitry.
The 34703 incorporates specific advanced protection features for use with high
power processors and controllers, including power-up and power-down sequencing
of the I/O and core supply voltages in relation to each other.
Features
• Wide input Operating Voltage Range: 2.8 V to 13.5 V
• Adjustable Output Voltages
• Continuous Core Voltage Supply Currents up to 10 A (with infrequent
excursions to 12 A permitted)
• Undervoltage Lockout
• Selectable Power Sequencing
• Programmable Watchdog Timer
• Voltage Margining via I2C Bus
• Overcurrent Protection
• Reset with Programmable Power-ON Delay
