Technical Data
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
to 32V, the 34710 is applicable to many commercial and industrial
applications using embedded MCUs.
A mode-selected 5.0 or 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)
