The LM5161QPWPRQ1 is an integrated power module (IPM) designed for high-performance DC-DC conversion. It integrates an inductor-based DC-DC converter with a high-speed PWM device. It reduces the design complexity and improves system reliability. This device operates from a wide input voltage range and offers complete power conversion solutions for high voltage and low voltage applications. This integrated solution simplifies the design process, reduces external components and increases the efficiency of the power system.

The LM5161QPWPRQ1 is a DC-DC switching regulator, which employs a synchronous rectifier to increase efficiency. It requires only a few external components, such as an inductor and a few capacitors and resistors to form a complete power supply. The converter has an adjustable output voltage and is capable of providing up to 1 A of output current. The converter can be used in either buck or boost configurations. It has an integrated power switch, enabling the system designer to implement control of the output voltage over time. Other features of this device include auto-start controller and integrated overvoltage protection. This device is housed in a small, leadless QFN18 package.

The LM5161QPWPRQ1 is designed for portable electronics, such as cellular phones and digital cameras. It is ideal for applications that require high efficiency and high power density in a very small form factor. The device can also be used in low voltage, low power applications such as battery-powered devices. The LM5161QPWPRQ1 can also be used for industrial control applications, where current requirements are modest and size is of paramount importance.

The LM5161QPWPRQ1 employs a synchronous rectifier to boost efficiency. The rectifier is driven by an integrated power switch and works together with an external inductor to convert the input voltage to the output voltage. It has a fixed switching frequency of ~100 kHz, and the output voltage can be adjusted between 0.8V to 5.5V. The current limit is programmable, allowing the device to be used as a low-current or high-current device. The output ripple is kept low due to the integrated high-speed PWM controller. The power-on reset circuit enables the device to be powered up without needing an external reset circuit.

The LM5161QPWPRQ1 also integrates overvoltage protection (OVP) for improved system reliability. The integrated OVP provides a better protection for the output voltage and prevents the output from overshooting. The other features such as auto-starting and Soft Start/Stop also help keep the output voltage within the design limits. The device is designed to meet the requirements of the automotive temperature ranges and is EMI tested to ensure minimum conducted EMI levels.

In summary, the LM5161QPWPRQ1 is the perfect integrated solution for small, portable and low power applications. It offers high efficiency, high power density and low external component count, making the design process much simpler. Additionally it has integrated overvoltage protection and FEATURES like auto-starting, Soft Start/Stop for improved system reliability. It is suitable for both low voltage and high voltage applications, and it is well-suited for both industrial control applications and end consumer electronics.
