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 Vor 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.
Features
• Efficient 5.0 V/3.3 V Buck Regulator
• Low Noise LDO Regulator (mode-selected 3.3V, 2.5V,1.8V, or
1.5V)
• On-Chip Thermal Shutdown Circuitry
• Supervisory Functions (Power-ON Reset and Error Reset
Circuitry)
• Sequenced I/O and Core Voltages
• Pb-Free Packaging Designated by Suffix Code EW
