The LTC1474CMS8#TRPBF is a synchronous, Step-Down DC-DC, Switching Regulator Module from Linear Technology. It is designed to provide high efficiency and low noise power conversion from an input voltage of between 4.5V and 48V to a programmable, regulated output voltage of up to 24V. This makes it an ideal choice for applications that require fast transient response, high accuracy, low output noise and low power dissipation in a wide variety of switch-mode power supply, point-of-load power, adaptive and regulated power supply, and post-regulation applications.

The LTC1474CMS8#TRPBF operates with a fixed frequency of 333kHz and uses a synchronous switching mechanism to deliver high accuracy and low output noise, while achieving high efficiency over a wide range of load and input voltage conditions. It has numerous features for circuit protection: over-temperature protection, soft-start, adjustable current limit protection, under-voltage lockout, and output disconnection. The module has an adjustable output voltage as low as 0.6V, making it suitable for powering DSPs, DACs, FPGAs and other low voltage ICs and peripherals.

The board also has several easy-to-use design features that make it applicable to a wide range of uses. The board has onboard jumpers that adjust the input and output voltage, allowing the output voltage to be adjusted to suit the requirements of the target application. Additionally, there is an adjustable current limit setting that can be set to limit the maximum current drawn from the power supply.

This board also features several advanced functionality that make it a great fit for complex applications. The accuracy of the output voltage is adjustable to ±1%. It features an automatic equalization of load lines that helps to minimize input and output noise in applications that require lower output noise. This feature ensures that ripple and inrush current remain low. Additionally, the output voltage is adjustable to ±10% of the target output voltage. This allows for the power supply to be tuned to the nominal application requirements.

The LTC1474CMS8#TRPBF is designed to provide reliable power supply applications with a large input voltage range and high efficiency. Its adjustable current limit and output voltage, its superior line and load regulation, and its adjustable current limit protection make it an ideal choice for applications that require fast transient response, high accuracy, and low output noise. It is suitable for DSPs, FPGAs, DACs and other low voltage digital ICs, as well as a wide variety of switch-mode power supply and post regulations applications.
