The LTC3407IDD-2#TRPBF voltage regulator is a DC to DC switched mode regulator that is commonly used for a wide range of applications. This converter is designed to deliver an efficient, constant output voltage regardless of the input voltage, current, load and temperature conditions. The LTC3407IDD-2#TRPBF is an efficient, highly versatile step-up converter that is ideal for powering mobile and embedded devices such as smartphones, tablets, automotive, industrial and medical applications.

The LTC3407IDD-2#TRPBF regulator operates by employing a synchronous buck-boost switching topology that consists of two internal power switches, a control loop and an internal power conversion stage. The two power switches alternately charge and discharge a storage inductor connected between the input and output capacitor. The current through the inductor is regulated by the internal control loop, and the inductor is used to store energy while charging and discharge while discharging.

In order to minimize the size of the internal components, an external storage capacitor is connected between the VIN and VOUT pins of the regulator. This capacitor is used to provide additional energy when the input voltage is below the regulated output voltage while preventing the output voltage to exceed the regulation value when the input voltage is above the regulated value. This ensures that the regulator operates efficiently even when the input voltage changes drastically and efficiently compensates for the output voltage drops due to the heavy load.

The LTC3407IDD-2#TRPBF voltage regulator operates over a wide input voltage range of 4.5V to 40V and offers adjustable output voltage of up to 40V with a maximum current rating of 1.2A. It also supports three different switching frequencies, including 1.6MHz, 2.25MHz and 4.5MHz. This allows designers to choose the optimal switching frequency depending on the application requirements. For example, when a low noise output is required, the lower switching frequency of 1.6MHz can be used.

The LTC3407IDD-2#TRPBF offers other features that makes it ideal for a wide range of applications. It features a soft start function that helps reduce the surge in current during startup and shutdown, over-voltage protection, under-voltage lockout, thermal shutdown and current limit protection. It also offers programmable tracking pre-regulation using external resistor divider. The device operates in a low quiescent current mode, consuming just 60mA.

The LTC3407IDD-2#TRPBF offers a wide range of benefits for a wide range of applications. Its wide input voltage range and adjustable output voltage makes it ideal for use in mobile and embedded devices. Its low operating current and wide range of protection features make it safe for use even in critical applications. With its feature-rich package, the LTC3407IDD-2#TRPBF is an ideal DC to DC regulator for both mobile and embedded applications.
