Technical Data

Dual Output DC-DC & Linear

Regulator IC

34710

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

to 32V, the 34710 is applicable to many commercial and industrial

applications using embedded MCUs.

DUAL OUTPUT DC-DC & LINEAR

REGULATOR

A mode-selected 5.0or 3.3V DC-DC switching regulator is

provided for board-level I/O and user circuitry up to 700mA. A linear

regulator provides mode-selected core supply voltages of either 3.3V,

2.5V,1.8V, or 1.5V at currents up to 500mA.

The supervisor circuitry ensures that the regulator outputs follow a

predetermined power-up and power-down sequence.

Features

• Efficient 5.0V/3.3V 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
