Power management integrated circuits (PMICs) are a new generation of integrated circuits that provide energy solutions for all kinds of system form factor designs, including voltage regulators, dc-dc switching regulators, and dc-dc converters. The LT1767EMS8-1.8#TRPBF is a high performance synchronous buck regulator PMIC integrated into a thermally enhanced 8-pin micro SMD package.

The LT1767EMS8-1.8#TRPBF belongs to the class of DC-DC Switching Regulators, which utilize one or more switching elements (such as transistors or FETs) to reduce the voltage level and provide regulated output from a limited DC source. The LT1767EMS8-1.8#TRPBF is intended for low noise, low power, and high efficiency applications. It is designed to support input voltages ranging from 2V to 15V, and can provide clean regulated outputs from 1.2V to 4.4V with 4.4A of output current.

The LT1767EMS8-1.8#TRPBF DC-DC switching regulator integrates a high-efficiency current-mode synchronous buck regulator, high-side and low-side FETs, current sensing, programmable soft-start, over-temperature protection and UVLO. The device operates at a switching frequency up to 1.5MHz, allowing the use of a smaller inductor and increasing loop bandwidth for improved transient response.

The LT1767EMS8-1.8#TRPBF can be used in a wide range of applications, including networked consumer electronics, communication infrastructure systems, SSDs, Portable Instruments, FPGA\'s and Networking LANs. It is an exceptionally versatile and reliable power switch for managing power supply to numerous consumer products.

The LT1767EMS8-1.8#TRPBF has an integrated non-overlapping control that prevents both MOSFETs from conducting at the same time, which helps to reduce output ripple. It also has an adjustable dead time control function that can be used to eliminate shoot through during normal operation and redundant pulse events on the MOSFETs during turn off.

The LT1767EMS8-1.8#TRPBF also features a synchronous rectification control feature. With this circuit, the high-side phaser is configured as a synchronous rectifier to reduce conduction losses in the power MOSFETs and increase power efficiency in the system. In addition, the device has an adjustable frequency for setting the switching frequency between 300 kHz and 1.5 MHz.

Finally, the LT1767EMS8-1.8#TRPBF has a programmable soft-start pin that initiates the voltage ramp up according to the user\'s desired target voltage. Additionally, the device features over-temperature protection and under-voltage lockout, which protect the circuit components against possible damage due to excessive load current or overvoltage.

In conclusion, the LT1767EMS8-1.8#TRPBF is a high performance synchronous buck regulator PMIC that is ideal for low noise, low power, and high efficiency applications. It provides a wide range of features, including adjustable dead time control, synchronous rectification control, and programmable soft-start.
