LM2590HVSX-5.0 is a step-down high voltage and high current DC-DC switching regulator from Texas Instruments. It is a portable, low-power, cost-effective switching regulator that is suitable for mobile phones, tablets, and any other devices that require a stable and reasonably low voltage supply for its operation or battery charging.
The LM2590HVSX-5.0 is a monolithic integrated circuit (IC) offers a total integrated system solution for controlling power in DC-DC converter applications. It also provides on-chip controls for all major topologies, including buck, boost and simultaneous buck/boost, with features such as over-temperature protection, thermal limiting, adjustable output voltages, output current monitoring and over-current protection.
The LM2590HVSX-5.0 utilizes a single-phase, non-synchronous buck topology and a “constant on-time” current-mode control, which is powered by an N-channel MOSFET, thereby allowing for a wide input voltage range and adjustable output voltage. The “constant on-time” feature ensures that the current-mode control loop maintains the same power-conversion efficiency regardless of input voltage or load current by self-adjusting the switching period depending on line and load conditions.
The LM2590HVSX-5.0 operates with a wide input voltage range of 3V to 30V and delivers up to 5A of output load current at an adjustable regulated output voltage up to 12V. The package of this IC is a 10-pin HTSSOP, which is designed to enable high density applications such as notebooks and mobile devices. The device is also fully protected against over-temperature, over-voltage, and under-voltage conditions with automatic soft-start circuitry.
The LM2590HVSX-5.0 also includes an integrated boundary protector and integrated series-current limit that protect the system from otherwise-fatal faults for a sustained fault current in excess of 5A. This is complemented by the integrated output disconnect function that provides system-level protection when the circuit’s input voltage rises above the output voltage. Due to its efficient and reliable operation, the LM2590HVSX-5.0 is ideal for a wide range of applications, including portable power supplies, automotive power systems, battery-operated electronic products, telecom infrastructure, and industrial applications.
In conclusion, the LM2590HVSX-5.0 is a highly integrated, well-configured DC-DC step-down switching regulator designed to meet the stringent requirements of power-sensitive applications. It offers high performance with its wide input voltage range, high efficiency, and high current ratings, while the integrated safety features of the device provide a higher level of reliability during operation. This makes it an ideal choice for various applications requiring high-performance and reliable power conversion.
