The LM2592HVSX-5.0/NOPB is a voltage regulator that belongs to the family of DC DC switching regulators designed for use in mobile or point-of-load applications. It offers an adjustable output voltage between 2.5V and 36V and can provide a maximum output current of up to 5.0A.The LM2592HVSX-5.0/NOPB is a two-stage converter that uses a high-side P-channel MOSFET as the synchronous switch and a low-side N-channel MOSFET as the synchronous rectifier. It offers fast transient response times and has a potted die construction for improved thermal performance.The LM2592HVSX-5.0/NOPB is designed to provide a constant voltage output over a wide input voltage range. It has a wide operating temperature range of -40°C to +125°C. It also features an adjustable soft-start feature and includes internal over-temperature and short-circuit protection.The LM2592HVSX-5.0/NOPB is ideal for applications that require a wide load range and fast transient response. This device can be used in battery-powered applications, such as mobile phones or tablets. The LM2592HVSX-5.0/NOPB also provides precise regulation of output voltage, making it suitable for point-of-load applications.In terms of working principles, the LM2592HVSX-5.0/NOPB has a two-stage, synchronous buck converter architecture. The first stage consists of the high-side P-channel MOSFET switch and the second stage consists of the low-side N-channel MOSFET rectifier. The two switches are synchronized and operate at a frequency determined by an internal oscillator.The P-channel MOSFET switches on during the rising edge of the oscillator’s waveform. This switch is used to regulate the output voltage of the circuit. As the switch is turned on, the output voltage is maintained at the desired level and the N-channel MOSFET turns off when the output voltage reaches the desired value. The P-channel MOSFET will then turn off and the N-channel MOSFET will turn on for the remainder of the rising edge. This process continues until the oscillator’s waveform reaches its valley, which occurs at the end of the rising edge.Additionally, the LM2592HVSX-5.0/NOPB has an adjustable soft-start feature that prevents inrush current when the converter is first turned on. This feature is enabled by an internal soft-start voltage that is added to the gate drive of the high-side MOSFET switch.The LM2592HVSX-5.0/NOPB has a wide operating temperature range and offers fast transient response times. It also features an adjustable soft-start feature and integrated over-temperature and short-circuit protection.The LM2592HVSX-5.0/NOPB is suitable for a variety of mobile and point-of-load applications, including battery-powered systems such as phones, tablets, and wearable devices. It offers precise and adjustable output voltage, fast transient response times, and excellent thermal performance.
