TPS5405DR Description

Short technical summary and product information.

The TPS5405DR from Texas Instruments is a monolithic non-synchronous step-down (buck) switching regulator designed for power management applications. It features a wide input voltage range from 6.5V to 28V and can deliver a fixed 5V output with a maximum continuous output current of 2A.

 

This regulator operates with a peak current-mode control and includes cycle-by-cycle over-current protection. It utilizes pulse skipping mode to achieve high light-load efficiency, exceeding 80% at 10mA loading. The switching frequency is adjustable from 50kHz to 1.1MHz, set by an external resistor, with a typical default frequency of 120kHz when the ROSC pin is left floating.

 

The TPS5405DR is available in an 8-pin SOIC package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). The device also incorporates features like adjustable soft start and switching node anti-ringing to ease EMI issues, making it a versatile choice for various DC/DC conversion needs.
