The LM25088MHX-2/NOPB is a device designed to enable efficient DC-to-DC power conversion. Developed by Texas Instruments, this switching controller is composed of an efficient synchronous rectifier, a high-side current sense, a low-side current sense, an adjustable low-side current limiting, and a precise voltage feedback amplifier. As such, it is designed as a power management integrated circuit (PMIC) and falls into the voltage regulator and DC-to-DC switching controller class of products. It is best-suited for battery-powered applications such as low-power computing and communications devices.

The LM25088MHX-2/NOPB utilizes a fixed operating frequency of 1.9MHz and offers an externally adjustable synchronization of up to 6MHz. As a result, the device can easily be configured to suit a variety of input/output settings and applications. Additionally, the LM25088MHX-2/NOPB provides excellent maximum duty cycle accuracy, a low-ripple output voltage, and an excellent ripple effect suppression. It is also capable of handling high output current values.

The LM25088MHX-2/NOPB works by converting the input voltage into a switched output. This is accomplished by a process of power conversion, where the input voltage is compared with a voltage reference and then used to switch a set of high-side and low-side power switches. By alternately connecting the output to the input and ground, the proportion of power transferred to the output is determined by the duty cycle of the switches. The synchronous rectifiers are used to reduce power losses when the output is switched between the high and low states.

The LM25088MHX-2/NOPB can provide a maximum output power of up to 22 watts of power. The device offers several integrated features, including high-side and low-side current sensing, adjustable current limiting, and a precise voltage feedback amplifier. These features allow the device to accurately adjust the output voltage, current, and power according to changes in the input voltage. Furthermore, the device includes additional features such as internal soft-start and compensation for improved system stability.

The LM25088MHX-2/NOPB is offered in several packages, including a 14-pin, 4 x 4mm QFN, a 14-pin, 4 x 4mm MLP, and a 14-pin TSSOP. The device is designed to operate with an input voltage range of 3.5V to 28V with an output voltage range of 0.9V to 20V. The device offers a wide range of protection features, including over-current, over-temperature, under-voltage lockout, bias, and over-voltage protections.

The LM25088MHX-2/NOPB is an excellent choice for a variety of applications, including mobile phones, battery-operated portable devices, and automotive applications. By using an efficient power conversion process and an array of integrated features, the LM25088MHX-2/NOPB offers excellent performance in terms of power conversion efficiency, power supply stability, and ripple effect suppression.
