DC-DC converters are electrical components used to convert a high voltage input to a moderate output voltage. The TPS84620RUQT, a wide-input, unregulated, buck DC-DC converter, is a reliable and cost-effective device suitable for automotive applications. It has a maximum output current of 6A and a switching frequency of up to 500 kHz. This application note covers the application field and working principle of TPS84620RUQT.
The TPS84620RUQT was designed for automotive vehicle networks. It is suitable for converting unregulated 12V automotive batteries into regulated 5V output. The device has an internal 40V MOSFET in a small QFN-20 package and is thermally enhanced for efficient heat dissipation. Furthermore, it provides a low-voltage start-up for correct regulation even with a low input voltage. It features fast transient response, tight line/load regulation and low quiescent current. The combination of its wide input voltage range and small package size make it an ideal solution for automotive applications.
The working principle of the TPS84620RUQT is based on a synchronous buck converter topology. It accepts an input voltage from 4.5V to 40V and regulates an output voltage of up to 5.5V. The device operates in the continuous conduction mode and uses peak current mode control to regulate the output voltage. The voltage is sensed at the OUT pin and compared to an internal reference. The converter\'s output is regulated by adjusting the duty cycle of the switching FETs. An internal oscillator is used to generate the switching frequency, which is adjustable up to 500 kHz.
The TPS84620RUQT has integrated protection features, such as undervoltage lockout, cycle-by-cycle current limiting, and thermal shutdown. This device also has an adjustable soft-start feature which can be used to reduce inrush current during the start-up. Additionally, the device integrates independent enable pins to control power-up and power-down sequencing.
In summary, the TPS84620RUQT is a wide-input, unregulated, buck DC-DC converter used for automotive applications. The device operates with a synchronous buck converter topology and fully supports peak current mode control, undervoltage lockout protection, cycle-by-cycle current limitation, and thermal overload protection. It features a wide input voltage range, fast transient response, low-quiescent current, tight line/load regulation, and adjustable soft-start/soft-stop. These features make the TPS84620RUQT an ideal solution for automotive applications.
