TPS62407QDRCRQ1 is an integrated synchronous-buck 5A DC-DC buck converter from Texas Instruments. This DC-DC buck converter can provide a wide range of voltage conversion with up to 95% energy efficiency at a low operating temperature, making it an ideal power management solution for portable applications such as 3D televisions, mobile phones, PDAs, and GPS systems. TPS62407QDRCRQ1 is a high-efficiency, dual-channel, ultra-low-power, synchronous buck regulator IC that operates from a wide supply voltage range of 3.2V to 25V, which is suitable for industrial, automotive, and telecom applications.

TPS62407QDRCRQ1 is a monolithic integrated circuit with ultra-low quiescent current and improved overload and thermal transient line regulation. The TPS62407QDRCRQ1 is an excellent choice to power digital cores, such as those in mobile phones and 3D television front-end circuits.

The TPS62407QDRCRQ1 integrates two modes (forced PWM and skip) and two channels of gate drivers with adjustable dead times. It incorporates unique features such as low-ripple, low dropout operation, -3 dB/decade line transient loading characteristics for both channels, and maximum output current limit enable/disable functionality. It features 2.5 V to 8 V output voltage range and delivers up to 1 MHz switching frequency. In a typical application, the TPS62407QDRCRQ1 requires only only six external components.

The TPS62407QDRCRQ1 is designed to meet the needs of demanding applications such as mPOS, gaming, white goods, audio, robotics, motors, wearable electronics, and RF transmitters. It features low startup and dropout current, adjustable soft-start ramp rate and an enable/disable function for both channels for shutdown and power savings.

The TPS62407QDRCRQ1 works by converting an input voltage to a fixed output voltage, or vice versa. It does this by measuring the input voltage and converting it to a lower voltage. The typical input is a 5V source and the output voltage can be adjusted from 2.5V to 8V with a resolution of 0.2% to 0.7%. This output voltage is achieved by using MOSFETs to switch the input voltage, resulting in a PWM signal. The PWM signal is then filtered and regulated to the desired output voltage. The DC-DC buck converter has two channels, allowing two outputs to be generated at the same time. The device can also be used to provide soft-start, over-voltage, over-current and over-temperature protection.

In summary, the TPS62407QDRCRQ1 is a synchronous buck 5A DC-DC buck converter which provides excellent power conversion efficiency and low operating temperature for portable applications. It provides a wide range of voltage conversion, output current limit enable and disable functionality, adjustable soft-start ramp rate and a wide supply voltage range from 3.2V to 25V. It features ultra-low quiescent current, improved overload and thermal transient line regulation and can deliver up to 1 MHz switching frequency.
