TPS62170EVM-627 is an evaluation module for DC/DC and AC/DC (off-line) SMPS. It is designed for the TPS62170, a synchronous monolithic buck converter, and is used to evaluate all of the device’s features. The output voltage is adjustable from 0.7V to 2.5V using an external resistor divider. The switching frequency can be adjusted between 300kHz and 1.2MHz by using an external resistor. In addition, the module contains all of the circuitry necessary to implement the synchronous buck topology.The TPS62170EVM-627 can be used in a variety of applications, including powering up DSPs and FPGAs, regulation supplies, and voltage conversion for notebook computer applications. The device is also suitable for automotive, industrial, and medical applications.The main components of the TPS62170EVM-627 are the TPS62170 buck synchronous converter, a 3.3V LDO regulator, and external components such as passive components, filters and opto-couplers. The TPS62170 synchronous buck regulator is a two-stage device with an internal PWM controller and synchronous MOSFETs. The internal PWM controller provides cycle-by-cycle current limiting, soft start, and thermal shutdown protection.The TPS62170EVM-627 evaluates the TPS62170 synchronous buck converterin three different scenarios: 9V-to-1.2V at 500mA, 9V-to-1.8V at 600mA, and 9V-to-2.5V at 800mA. Output voltage is adjustable from 0.7V to 2.5V using an external resistor divider. The maximum current at each output voltage is determined by the external components used in the circuit. The switching frequency can be adjusted from 300 kHz to 1.2MHz.The output voltage of the TPS62170EVM-627 is regulated by the combination of an internal voltage feedback loop and external components used in the circuit. The external components include a resistor divider and capacitors. The voltage feedback loop is composed of the voltage divider, error amplifier, compensation network, ripple filter, and driver. The external components connected to the feedback loop sets the reference voltage, and with it the output voltage of the device.In addition, the TPS62170EVM-627 evaluation module offers different protection features. It includes temperature protection, short-circuit protection, over-current protection, and over-voltage protection. These safety features are designed to protect both the device and the system.The TPS62170EVM-627 evaluation module is an excellent choice for evaluating the TPS62170 synchronous buck converter. It provides adjustable output voltage and switching frequency to suit different applications, as well as safety features to keep the system protected. In summary, the TPS62170EVM-627 evaluation module is the perfect tool for evaluating the performance and features of the TPS62170 synchronous buck converter.
