DESCRIPTION
The TPS70358 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 applications with power sequencing requirement.
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.
