Preliminary Information Adjustable Dual Output Switching Power Supply
The 34710 is a dual-output power
regulator IC that integrates a switching
regulator, a linear
regulator, supervisor circuitry, and a power supply sequencer. With a wide operating input voltage range of 12 V to 32 V and robust temperature limits, the 34710 is applicable in many commercial and industrial applications that use an MCU.

ADJUSTABLE DUAL OUTPUT SWITCHING POWER SUPPLY
Freescale Semiconductor, Inc...
A user-selectable 5.0 V/3.3 V buck 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 3.3 V/2.5 V/1.8 V/1.5 V linear voltage
regulator that can supply up to 500 mA. The switching and linear
regulator output voltage are determined through three digital input mode terminals that can be controlled by an MCU. Features High-Current Adjustable 5.0 V/3.3 V Switching
