LTC3126IUFD#TRPBF is a DC-DC switching regulator integrated circuit (IC) designed for high performance and efficient power management. This high-closed-loop-bandwidth monolithic regulator provides point-of-load conversion for microprocessors and DSPs. It is available in a thermally enhanced MSOP-14 package. The device is ideal for use in harsh environments, being capable of fully robust operation over a wide range of temperatures.

The design is based on analog switching technology, making it suitable for high-frequency, low-noise applications. It is a single feature, one-loop regulator, offering a wide range of adjustable output voltages and wide input voltage ranges. The IC employs an external switch, plus an internal low-impedance converter to allow millivolt level output regulation over a wide input voltage range and various load conditions.

This device also offers both limited power and time-based over temperature protection as a safety feature. The low quiescent current and low power consumption of the IC allows for increased power efficiency at high voltages, even up to wide-range input voltages.

Working principle of LTC3126IUFD#TRPBF:

The IC operates by using an external switch and an internal low-impedance converter. When power is supplied to the IC, the internal controller turns the external switch on and off according to the output voltage set-point, allowing the input power to be converted as required. The input voltage is filtered and regulated to the output voltage, ensuring it is stable and consistent, then fed to the output.

When the input voltage drops below a certain level, the LTC3126IUFD#TRPBF can be configured to shut down and protect itself, reducing risk of damage. Additionally, it provides the option of an adjustable frequency control, allowing it to operate at frequencies up to 1MHz, allowing conversion from even very low voltage inputs.

Application Field of LTC3126IUFD#TRPBF:

The LTC3126IUFD#TRPBF DC-DC switching regulator can be used in a variety of scenarios. Due to its low power consumption, point-of-load conversion, wide input voltage range, and temperature-resistant properties, it can be used in devices operating in harsh environments or exposed to extreme temperatures. It can also be used as a cost-effective solution in applications such as laptops, battery chargers, and hand-held or wearable devices, or even in high-end hobbyist or engineering projects.

The flexibility provided by the LTC3126IUFD#TRPBF switching regulator makes it a suitable candidate for low-power applications, such as laptop computers and other portable devices, where size and weight need to be kept to a minimum. The adjustable frequency control also allows for improved effiency of the overall power management system. Besides, the ability to operate across multiple input and output voltages makes the IC ideal for powering high-performance microprocessors and DSPs.

In summary, the LTC3126IUFD#TRPBF DC-DC switching regulator is an incredibly efficient and highly robust device, capable of providing point-of-load conversion from even the most extreme environments. Its low quiescent current and low power consumption make it ideal for use in devices such as laptops and battery chargers or even in high-end hobbyist or engineering projects. With its adjustable frequency control, multiple input and output voltages, and temperature-resistant design, the LTC3126IUFD#TRPBF is sure to deliver a reliable, efficient, and cost-effective solution for any power management application.
