34710

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC34710 Rev 1.0, 04/2004 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. 34710 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 Regulator Low Noise User-Selectable 3.3 V/2.5 V/1.8 V/1.5 V Linear Regulator On-Chip Thermal Shutdown and Error Reset Circuitry Supervisory Functions (Power-ON Reset and Error Reset Circuitry) Sequenced I/O and Core Voltages Pb-Free Packaging Designated by Suffix Code EW EW (Pb-FREE) SUFFIX CASE 1324-02 32-LEAD SOICW-EP ORDERING INFORMATION Device PC34710EW/R2 Temperature Range (TA) 0°C to 85°C Packag...
