23 DESCRIPTION
TPS707xx family devices are designed to provide a
complete power management solution for the
TMS320в„ў DSP family, processor power, ASIC,
FPGA, and digital applications where dual output
voltage regulators are required. Easy programmability
of the sequencing function makes the TPS707xx
family ideal for any TMS320 DSP applications with
power sequencing requirements. Differentiated
features, such as accuracy, fast transient response,
SVS supervisory circuit, manual reset inputs, and an
enable function, provide a complete system solution. …
