The LTC3548EMSE#TRPBF is a high-performance, fixed frequency, step-down switching regulator with an external sense pin. It features an extremely low operating current, high efficiency, and wide input operating range. It is suitable for a wide range of applications, including automotive, industrial, and consumer electronics.

The LTC3548EMSE#TRPBF operates from an input voltage of 1.8 V to 28 V and can support input voltages up to 33 V for brief periods, making it suitable for use in a wide range of automotive, consumer, and industrial applications. Its 3A DC output current rating, low dropout voltage and integrated switching FET makes it an ideal solution for space-constrained point-of-load regulation applications.

The LTC3548EMSE#TRPBF provides a highly efficient, fixed frequency step-down switching regulator with an adjustable output voltage from 0.6V to VIN. It switches at a selectable frequency of 250kHz, 500kHz, 750kHz, or 1MHz, allowing for maximum system flexibility. The switching frequency is user-programmable via an external resistor, with an internal oscillator providing low-noise operation at all frequencies.

The regulator also features a top-side external sense pin which allows more accurate voltage regulation than what can be achieved with the conventional bottom-side sense pin. This sense pin can be used to provide either remote sensing or localized sensing near the load, improving regulation accuracy and transient response. The LTC3548EMSE#TRPBF also allows for higher current output than would be available with the conventional bottom-side sense pin.

In addition, the LTC3548EMSE#TRPBF also features several advanced features such as input undervoltage lock-out, output overcurrent protection, and over-temperature protection, which are all included on-chip. The output overcurrent protection is adjustable via an external resistor, which allows designers to tailor the output current limits for their specific application. The LTC3548EMSE#TRPBF also includes a Power Good signal, which allows for system monitoring of the output voltage.

The LTC3548EMSE#TRPBF is a great choice for any project that requires a reliable, efficient, and easy-to-implement DC-DC step-down switching regulator with an external sense pin. Its advanced features and wide operating range make it a great choice for applications in the automotive, industrial, and consumer electronics markets.
