8 Detailed Description
8.1 Overview
The TPS8268x is a complete DC/DC step-down power supply intended for small size and low profile
applications. Included in the package are the switching regulator, inductor and input/output capacitors. It is a
complete Plug & Play Solution, meaning typically no additional components are required to finish the design.
Integration of all required passive components enables a tiny solution size of only 6.7mm2. The converter
operates with fixed frequency pulse width modulation (PWM).
The TPS8268x integrates an input current limit to protect the device against heavy load or short circuits and
features an undervoltage lockout circuit to prevent the device from misoperation at low input voltages.

8.3 Feature Description
8.3.1 Soft Start
The TPS8268x has an internal soft start circuit that controls the ramp up of the output voltage. Once the
converter is enabled and the input voltage is above the undervoltage lockout threshold VUVLO, the output voltage
ramps up to 95% of its nominal value within tRamp of typ. 150μs. This ensures a controlled ramp up of the output
voltage and limits the input voltage drop when a battery or a high-impedance power source is connected to the
input of the DC/DC converter.
The inrush current during start-up is directly related to the effective capacitance and load present at the output of
the converter.
