LT3645EUD#TRPBF is a linear and switching voltage regulator manufactured by Linear Technology. It is used in a variety of power management and regulation applications. The LT3645EUD#TRPBF features integrated low-dropout (LDO) linear regulators and a flexible dual-phase interleaved or synchronous buck regulator. The device is designed to minimize global power consumption, reduce external component count and provide excellent transient response while delivering up to 6.0A of current.

The device offers a wide 0.8V-5.5V input voltage range and an output voltage adjustable from 0.6V to 5.5V. It has excellent protection features such as short circuit, thermal shutdown and over-current protection. The built-in thermal shut-down circuitry prevents the device from operating when the temperature exceeds the absolute maximum rating. This device is specified for operation over the extended temperature range (-40°C to +120°C).

The LT3645EUD#TRPBF features a low input voltage and low quiescent current of only 20μA in standby mode. Its high efficiency allows the device to regulate a wide range of output currents from 0.2A to 6.0A. In addition, the device has integrated soft start and a programmable power-ok threshold. It is also capable of consuming very low power at light loads.

The LT3645EUD#TRPBF can operate in PWM, PFM and forced-PWM mode, allowing users to adjust the output voltage and current. In addition, the device supports an adjustable switching frequency up to 1.2MHz. It also has a feature that allows user to control the output voltage slew rate.

The LT3645EUD#TRPBF features a selectable battery charge mode, which can be used in combination with the power-good output. This feature simplifies adding a battery-charging system to a power system, as the device provides all the required features for accurate charging control. The device also supports power-good output as well as an LED mode which allows the device to serve as a simple LED driver, allowing the user to set the LED brightness level.

In terms of safety and reliability, the LT3645EUD#TRPBF offers immune to noise on the power and feedback signals. It is certified to meet safety standards including UL and CSA, as well as EMC standards including EN55032 and CISPR32. It comes in a 20-pin TSSOP package, and is available in a lead-free, RoHS compliant package.

Overall, the LT3645EUD#TRPBF is an ideal voltage regulator for power management and regulation in industrial, automotive, and medical applications due to its wide input voltage range, low quiescent current, high efficiency, and excellent protection features. It is robust, reliable, and cost-effective, making it an ideal option for many low- to mid-power applications.
