Description

The 34710 is a dual-output power regulator IC integrating a switching regulator, linear regulator, supervisory circuitry, and power supply sequencing circuitry. With a wide operating input voltage range of 13 V to 32 V and 0°C to 85°C temperature limits, the 34710 is applicable to many commercial and industrial applications using embedded MCUs.

A user-selectable 5.0 V / 3.3 V buck DC-DC switching regulator is provided for board-level I/O and user circuitry up to 700 mA. The linear regulator of 34710 provides MCU core supply voltages selectable aseither 3.3V, 2.5V, 1.8V, or 1.5V at currents up to 500 mA. The switching and linear regulator output voltages are set via three digital input mode terminals.
