Join our teamThe 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.
