www.DataSheet4U.com Freescale Semiconductor Document order number: Technical Data MC34710 Rev. 3.0, 3/2006 Dual Output DC-DC & Linear Regulator IC The 34710 is a dual-output power regulator IC integrating switching regulator, linear regulator, supervisory and power supply sequencing circuitry. With a wide operating input voltage range of 13 V to 32 V, the 34710 is applicable to many commercial and industrial applications using embedded MCUs. A mode-selected 5.0 V or 3.3 V DC-DC switching regulator is provided for board-level I/O and user circuitry up to 700 mA. A linear regulator provides mode-selected core supply voltages of either 3.3V, 2.5V, 1.8V, or 1.5V at currents up to 500 mA. The supervisor circuitry ensures that the regulator outputs follow a predetermined power-up and power-down sequence.
