The Texas Instruments TPS62362EVM-655 is an evaluation module (EVM) designed to evaluate and demonstrate the features of the TPS62362. The TPS62362EVM-655 is a constant-frequency, current-mode, step-down converter with high efficiency and fast transient response.

The TPS62362EVM-655 belongs to the Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS. It is a 2A, 42V, high efficiency, fixed frequency DC / DC step down switching regulator with operating frequency of 1.2MHz. Maximum current is 3A with adjustable output voltage from 0.4V to 5.25V at efficiency of 90%. It has low noise, fast transient response, good accuracy, low standby quiescent current and adjustable switching frequency.

The TPS62362EVM-655 application field is mainly used in high efficiency power supplies and high power portable applications. The TPS62362EVM-655 is also suitable for battery powered and automotive applications. Its wide input voltage range of 2.2V to 42V and its operating temperature range of -40°C to +150°C make it ideal for many applications.

The TPS62362EVM-655 works on the principle of PFM (Pulse Frequency Modulation) and PWM (Pulse Width Modulation). In PFM mode (PFM soft-start), the duty cycle is adjusted to regulate the output voltage. The output voltage is proportional to the duty cycle. In PWM mode (PWM soft-start), the frequency is adjusted to regulate the output voltage. The output voltage is inversely proportional to the frequency.

The TPS62362EVM-655 has an internal 5.75V linear regulator to drive the gate of the external MOSFET. The internal gate driver provides fast transient response and accurate current-limit protection. The TPS62362EVM-655 also features over-temperature protection, output voltage feedback, and a programmable current-limit input.

The TPS62362EVM-655 is designed to be primarily used as a reference design tool for the TPS62362 step-down switching regulator. It simplifies the evaluation process of the regulator and helps to reduce development time. It can also be used to conceptualize various loads, as well as providing a reference point for the system designer.
