The product is designed to integrate smoothly into a variety of potential applications. It is designed to provide regulated output voltages from an unregulated input voltage within a wide input and output voltage range.

The LM3480IM3X-3.3 is a Power Management Integrated Circuit (PMIC) that can manage voltage in general-purpose applications, such as lighting, displays, automotive, industrial, and consumer designs. As part of the linear voltage regulator family, this device is especially useful in controlling low-power electronic systems. It also helps reduce power consumption and power supply noise.

The primary application field of the LM3480IM3X-3.3 is in controlling voltage regulation to deliver required power levels with the lowest level of power consumption. The device can support a wide variety of operating temperatures that range between -40°C to 85°C. It can be used in a variety of different output voltage ranges.

The LM3480IM3X-3.3 is a linear voltage regulator with an adjustable/fixed output voltage. It employs a three-terminal pinout package with an integrated power MOSFET to provide high-efficiency regulation. The source terminal of the MOSFET receiving the regulated output voltage is connected to the output terminal by the internal compensation network. The sense input connected to the regulator allows the sense resistor to sense the output voltage and adjust the on-time of the power MOSFET.

The working principle of the LM3480IM3X-3.3 is based on the duty cycle control method. During the on-time, the MOSFET drives the output voltage towards the regulated voltage, meanwhile the PWM Duty-cycle is adjusted to achieve a constant regulated output. During the off-time, the output voltage is discharged, and the cycle starts to repeat. To ensure precise and durable voltage regulation, the LM3480IM3X-3.3 applies advanced line compensation and loop compensation, as well as soft-start and precise current-limit protection.

The LM3480IM3X-3.3 is designed to provide precise voltage regulation with broadened operating temperature range, while keeping noise and power consumption levels as low as possible. It offers a safe and reliable power management solution that is ideal for many sensitive applications, including low-voltage power supply design, automotive, industrial, consumer, lighting, displays, and other applications.
