The TPS65235EVM-694 is an evaluation board module that is part of TI’s DC/DC & AC/DC Off-Line SMPS family. It is designed to enable designers to quickly and easily evaluate TI’s TPS65235EVM-694 device, a Synchronous Buck/Boost Converter. The TPS65235EVM-694 device is used to provide efficient power delivery to mobile and non-mobile battery-powered systems.

The input voltage range of the TPS65235EVM-694 is from 4.5 V to 36 V and the output voltage is adjustable from 0.8 V to 5.5 V. The integrated power switch has a peak current limit of 3 A with a typical operating frequency of 500 kHz. Its built-in power management system allows for operating at peak efficiency with a minimum of parts.

The working principle of the TPS65235EVM-694 is based on a synchronous buck/boost voltage regulator. The input voltage is converted to an intermediate voltage (Vint) using a buck regulator. The output voltage is then regulated by a boost regulator. The output stage of a synchronous buck/boost voltage regulator works by switching the power switch on and off at a certain frequency. When the power switch is closed, energy is delivered from an input voltage and stored in the inductor. When the power switch is opened, the energy stored in the inductor is transferred to the output voltage. This cycle repeats, resulting in a regulated output voltage.

The TPS65235EV-694 has integrated voltage, current and power monitoring features. The integrated monitoring features work in conjunction with the feedback circuit to ensure that the output voltage stays within required output voltage tolerances. The particular values of the feedback components used (voltage, current and power) is preprogrammed in the device, but can be adjusted via the device\'s configuration registers.

The TPS65235EVM-694 evaluation board also has an integrated set of EMI Noise Reduction components that enables designers to reduce EMI-related noise. The components work by providing a path for EMI-related noise to be diverted away from the output voltage. The particular combination of components used can be adjusted via the device\'s configuration registers.

In conclusion, the TPS65235EVM-694 evaluation board is part of TI’s DC/DC & AC/DC Off-Line SMPS family and enables designers to quickly and easily evaluate TI’s TPS65235EVM-694 device, a Synchronous Buck/Boost Converter. It has an input voltage range of 4.5 V to 36 V and an output voltage that is adjustable from 0.8 V to 5.5 V. It has an integrated power switch with a peak current limit of 3 A with a typical operating frequency of 500 kHz. Its integrated power management system, EMI Noise Reduction components and integrated voltage, current and power monitoring features make it a versatile and powerful evaluation board ideal for mobile and non-mobile battery-powered systems.
