Features

The device integrates a range of features designed to make it highly efficient and reliable. It utilizes synchronous rectification to maximize efficiency while operating at up to 93% efficiency. The synchronous clock switch automatically adjusts the switching frequency between 200-550KHz in order to maximize efficiency at all loads. It also includes an I2C interface for monitoring and controlling voltage, current, and temperature.

Working Principle

The TPS610995YFFR uses a buck topology converter to work as a fixed-frequency step-down DC/DC converter. The device uses an internal MOSFET switch and charge pump to convert the input voltage from an unregulated DC source to a regulated output. The device first rectifies and converts the input voltage to a high-voltage DC voltage. This voltage is then used to switch the internal MOSFET on and off, thus controlling the output voltage. During the on-state, the MOSFET is switched off, which passes the input voltage to the output. During the off-state, the stored charge pump is then used to keep the internal MOSFET on, thus controlling the output voltage. The device uses an internal compensation network to control the switching frequency and also has an external control component to further adjust the switching frequency and/or current limit.

Conclusion

The TPS610995YFFR is a high-performance, efficient, and compact DC/DC switching regulator ideal for a variety of applications from hard disk drives, servo motors, and industrial printers, to automotive components, electronic modules, and more. It utilizes synchronous rectification and integrated current and temperature monitoring, making it an excellent choice for a wide range of applications.
