The 34710 is a dual-output power IC that integrates a switching regulator, linear regulator, supervisory function, and a power supply sequencer. With a wide input voltage range of 13V to 32V and robust temperature limits, the 34710 is applicable in many commercial and industrial applications that use an MCU.
A user-selectable 5.0V / 3.3V switching regulator is provided for board-level I/Os and user circuitry. The regulator is capable of delivering up to 1.0 A. The MCU core voltage is an adjustable 3.3V / 2.5V / 1.8V / 1.5V linear voltage regulator that can handle up to 500mA.
The switching and linear regulator output voltages are determined through three digital input mode terminals that can be controlled by an MCU.
