TheTPS54335AEVM-010 is an evaluation module for Texas Instruments, TPS54335 switching voltage regulator.

The module is primarily designed to demonstrate the capabilities of the TPS54335, which is a high-frequency synchronous buck converter that delivers up to 6 A of continuous current and has a wide input and output voltage range. Additionally, the module also provides onboard load adjustment and monitoring connections, allowing for additional functionality and features to be explored.

The TPS54335AEVM-010 is designed for use as an off-line, DC/DC and AC/DC SMPS (switched-mode power supply) evaluation board. Its wide input and output voltage range make it suitable for a variety of different applications, ranging from power supply and voltage regulator circuits, to power conditioning and distributed power systems. Its power management capabilities enable a wide range of power solutions to be developed.

The TPS54335AEVM-010 integrates the TPS54335, a high-efficiency synchronous buck converter with an input voltage range of 8 V ~ 14 V and an adjustable output voltage of 0.25 V ~ 5.5 V. The integrated synchronous buck converter offers low EMI generation and efficiency up to 95%. This module also implements an internal PMOSFET switch with a nominal breakdown voltage of 28 V, which allows the use of capacitors and inductors with low ESR values.

The working principle of the TPS54335AEVM-010 is based on the “PWM” (Pulse-Width Modulation) technique. This technique enables the module to switch 16 kHz, resulting in radiated EMI noise being reduced to a minimum. Furthermore, the module offers synchronous rectification with a low-voltage Schottky diode, that helps to reduce the power dissipation during operation.

The module also includes an adjustable load regulator, allowing the user to adjust the energy consumption of the system. Additionally, the module also includes monitoring points that allow for current and voltage measurements to be taken for deeper diagnostics of the module’s operation.

In summary, the TPS54335AEVM-010 is an off-line, DC/DC and AC/DC SMPS evaluation board built around the TPS54335 switching voltage regulator. Providing an adjustable output voltage range of 0.25 V ~ 5.5 V, the module offers a wide input voltage range of 8 V ~ 14 V and provides onboard load adjustment and monitoring connections for further functionality and exploration. Operating using the PWM (Pulse-Width Modulation) technique, the module also includes a low-voltage Schottky diode and adjustable load regulator, enabling high-efficiency operation and diagnostic capabilities.
