The LTC3417EDHC#TRPBF is a step-down high-efficiency switch mode voltage regulator with programmable switching frequency, temperature-dependent frequency compensation, and very low quiescent current. The device is designed to provide power to low voltage, high current loads. It can be used in a variety of applications such as Ultrabooks and notebooks, mobile phones, consumer products, and industrial equipment.

When the input voltage is greater than the voltage to be provided to the load, the LTC3417EDHC#TRPBF switches at a fixed frequency of 2.3MHz. The switching frequency can be reduced to between 10kHz and 2.3MHz by reducing the value of an external resistor. This switch frequency can be increased or decreased depending on the load requirement and the ambient temperature.

The device operates as a non-synchronous buck regulator with a voltage loop consisting of two resistors, a capacitor, and two transistor switches. The voltage loop detects the output voltage and adjusts the current through the switch to keep the output constant. This ensures that the output voltage is regulated despite variations in input voltage and load current. The LTC3417EDHC#TRPBF also features a max-current foldback protection circuit to protect against current overloads and short-circuits.

The LTC3417EDHC#TRPBF operates at a high efficiency due to its low quiescent current. This low quiescent current reduces power losses and helps the device to maintain its high efficiency. The LTC3417EDHC#TRPBF also features a programmable under-voltage lockout circuit to prevent the device from starting up in the event of a low input power supply. This feature makes the device suitable for automotive and industrial applications.

The LTC3417EDHC#TRPBF is available in a 16-pin, thin-shrink small package, making it suitable for space-constrained applications. The device is rated for input voltage range of 2.3V to 26V and can provide up to 3A of load current. It also has an adjustable output voltage ranging from 0.6V to 20V.

In summary, the LTC3417EDHC#TRPBF is a high-efficiency, 120 kHz to 2.3 MHz step-down switch mode regulator which is suitable for high power automotive, consumer and industrial applications. This device provides excellent conversion efficiency with low quiescent current, as well as programmable under-voltage lockout and max-current foldback protection. It can be used in space-constrained applications due to its small package size.
