Introduction to the TPS62260DRVR
The TPS62260DRVR is an ultra-compact, 1.5 A step-down DC/DC switch-mode power converter optimized for space-sensitive, low power applications. This power module is especially designed to reduce component count and free up board space, providing a cost-effective, reliable and space-saving alternative to discrete designs. It offers a wide input voltage range and features a fixed switching frequency for ease of use and compatibility.
Application Field
The TPS62260DRVR, as a DC/DC switching regulator, is ideal for applications requiring maximum efficiency in a simple, space-saving design. It is suitable for a wide range of applications in the computing, communications, and consumer markets, such as powering USB ports and small, embedded systems. The 1.5A output current makes it suitable for applications such as portable media players, smartphones, and other embedded systems requiring a compact and efficient power solution.
Working Principle
The TPS62260DRVR is a non-synchronous buck converter that employs pulse width modulation (PWM) as its control input. The power device is a FET and the current sense resistor is employed in the feedback loop to regulate the internal switching frequency. The voltage mode control architecture allows for easy compensation and the internal compensation loop provides excellent transient response. An over-voltage protection (OVP) circuit is integrated in the device and the over-temperature protection (OTP) is also included. The operating frequency is fixed at 1MHz and can be further adjustable by 3 external resistors. The current limit is set by an external resistor divider.
The TPS62260DRVR includes an internal compensation network that simplifies setting up the loop compensation and transient response. An external resistor can be used to adjust the turn-on time, which is especially useful for applications that require very fast output voltage transient response.
The external UVLO (Under Voltage Lock Out) experience a slow rising to allow quick start-up and to ensure over-current protection during device operation without input under-voltage shutdown. The soft-start control is set internally and requires no external components. The device also gets out of soft-start mode in the event of an OCP (over-current protection) or input voltage drop.
Conclusion
The TPS62260DRVR is a compact, high performance, and cost-effective DC/DC switching regulator optimized for space-sensitive, low power applications. It has a wide input voltage range, fixed switching frequency, and easy to use design features. The 1.5A output current makes it ideal for powering USB ports and other small embedded systems while its voltage mode control architecture and internal compensation loop provide excellent transient response. This makes the device a great solution for applications requiring maximum efficiency and space savings.
