The LM2825HN-ADJ DC-DC switching regulator is a voltage regulator that offers low cost, high power, and small size. It operates in one of two modes: pulse-width modulation (PWM) or switch mode. In PWM mode, the regulator controls the duty cycle of the output voltage, while in switch mode the regulator would switch between one of two output voltages, depending on the load.The LM2825HN-ADJ has a wide, single input voltage range of 3 V to 15 V and can output fixed voltages of 1.5 V to 14 V. The regulator can be adjusted using an on-board trim potentiometer, making it suitable for applications that require fine tuning of output voltage and power.When used in switch mode, the LM2825HN-ADJ provides up to 1 A of continuous output current, with an additional 2 A of peak current available for short durations. The regulator features a PFM/PWM (pulse-width modulation) switching frequency of up to 1.25 MHz and integrated over-current, over-temperature, and reverse current protection.It is designed to be used in both linear and switching modes, and has a high efficiency rating in all operating modes. The switching frequency can be adjusted via an external resistor and capacitor, allowing for optimization of efficiency, noise, and power loss.When used in linear mode, the LM2825HN-ADJ will provide around 500 mA of continuous output current. The regulator supports a wide input voltage range of 7.5 to 15 V and can be adjusted over an output voltage range of 1.5 V to 14 V. The output voltage can be configured via an on-board resistor divider and can be further fine-tuned by an external trim potentiometer.The regulator also has an integrated reverse current protection circuit and will shut down when the output voltage exceeds or drops below certain limits. The LM2825HN-ADJ is available in a TO-263 (DPAK) package, making it suitable for applications with limited space requirements.The LM2825HN-ADJ is a great choice for applications that require an adjustable voltage regulator with low cost, high power, and small size. The integrated protections and range of adjustable features make it suitable for a variety of different applications.Overall, the LM2825HN-ADJ is an excellent choice for applications that require a high power, low cost, adjustable voltage regulator. It features adjustable PWM/PFM switching frequency, integrated protections, and wide input and adjustable output voltage range, making it suitable for a variety of different applications.
