FEATURES

DESCRIPTION

•

Dual Output Voltages for Split-Supply

The TPS703xx family of devices is designed to

provide a complete power management solution for

TI DSP, processor power, ASIC, FPGA, and digital

applications where dual output voltage regulators are

required. Easy programmability of the sequencing

function makes this family ideal for any TI DSP

application with power sequencing requirements.

Differentiated features, such as accuracy, fast

transient response, SVS supervisory circuit (power-on

reset), manual reset inputs, and enable function,

provide a complete system solution.

Applications

•

Independent Enable Functions (See Part

Number TPS704xx for Independent Enabling of

Each Output)

•

Output Current Range of 1 A on Regulator 1

and 2A on Regulator 2

•

Fast Transient Response

Voltage Options: 3.3 V/2.5 V, 3.3 V/1.8 V, 3.3

V/1.5 V, 3.3 V/1.2 V, and Dual Adjustable

Outputs
