Description
The TPS62400DRCR is a dual step-down (buck) converter from Texas Instruments, designed for efficient power management in portable and battery-powered applications. It integrates two independent synchronous buck converters with a fixed-frequency operation of 2.25 MHz, allowing for high efficiency and lower external component sizes. The device supports an input voltage range from 2.5 V to 6 V, making it suitable for lithium-ion battery applications.
Each converter can deliver up to 400 mA of output current, with output voltages adjustable via an external resistor divider. The TPS62400DRCR features low quiescent current, fast transient response, and excellent line and load regulation. Additionally, it incorporates power-saving features such as a power-save mode for light loads, reducing power consumption and extending battery life.
The chip is housed in a small, thermally efficient 10-pin VSON package, measuring 3 mm x 3 mm, making it ideal for space-constrained designs. It also includes features like thermal shutdown protection and overcurrent protection to ensure reliable operation.
