Analog Devices’ LM25017SDE/NOPB is an integrated DC-DC switching regulator that delivers higher performance than traditional solutions. It features the latest Generation 4 architecture, the industry-leading power transfer efficiency, and integrated MOSFETs for high-precision regulation. The device is configurable for either step-down or step-up/down operation, and it has a wide input voltage range of 4.5V to 42V. The outputs can be configured for any voltage up to 24V, making it suitable for a wide range of applications.

The LM25017SDE/NOPB provides the flexibility of configurable switching frequency up to 1MHz. Its built-in circuit protection features include Output Over-Voltage (OVP), Frequency Reduction, Thermal Shutdown, and short-circuit protection. The step-up/down feature makes it possible to regulate output voltages higher or lower than the input voltage, while still achieving high-performance operation.

The LM25017SDE/NOPB features a proprietary current-mode architecture, which provides excellent voltage regulation while reducing ripple and output noise. The device includes an integrated high-frequency control oscillator, enabling the user to select the frequency at which the MOSFETs switch. By adjusting the frequency, the user can optimize the power transfer efficiency, reduce component count, and simplify the external component requirements.

The included soft-start circuitry ensures that the voltage ramps up slowly and prevents any in-rush current at startup. This feature is especially useful in applications where the output voltage is substantially higher than the input voltage. The frequency reduction feature reduces the switching frequency when the output current is low, which helps to decrease power dissipation.

The LM25017SDE/NOPB is a highly integrated and efficient DC-DC switching regulator, designed to save cost and board space. It is ideal for a wide range of applications, including automotive, industrial, and consumer electronics. With its high performance and small package size, it is suited for high-power, medium-voltage, and low-noise applications.
