The TPS51397ARJER from Texas Instruments is a monolithic 10A synchronous buck converter featuring integrated MOSFETs for high efficiency and reduced component count. It utilizes the D-CAP3™ control architecture, providing fast transient response and excellent line and load regulation with internal compensation.
This converter supports a wide input voltage range of 4.5V to 24V and an output voltage range from 0.6V to 5.5V, making it suitable for various applications including notebook and PC computers, ultrabooks, and industrial PCs. The device includes ULQ™ (Ultra Low Quiescent) operation, drawing only 110 μA, which is beneficial for extending battery life during system standby.
Key features include selectable switching frequencies of 500 kHz and 800 kHz, adjustable soft-start time with a default internal 1.2 ms, and integrated power-good indication. It also offers built-in output discharge functionality and comprehensive protection features such as cycle-by-cycle overcurrent protection, latched output OV/UV protections, and non-latched UVLO and OT protections. The TPS51397ARJER is available in a compact 20-pin 3.0-mm x 3.0-mm HotRod™ VQFN package, operating within a junction temperature range of -40°C to 125°C.
