LT3758IDD#TRPBF

The LT3758IDD#TRPBF is a DC to DC switching controller designed to operate switching regulators with minimal external components and high efficiency. It is a part of the Linear Technology family of switch mode power supply (SMPS) controllers, and it has a wide range of applications in various power systems.

This DC to DC switching controller operates with a wide input voltage range of 4.75V to 28V, allowing it to provide power rails to different devices. The LT3758IDD#TRPBF has a cycle-by-cycle current limit, a programmable constant-on time control, and a power good signal for output voltage regulation. It also features frequency bandwidth control, overvoltage protection (OVP) and thermal shutdown (TSD).

The LT3758IDD#TRPBF is intended for use in applications where high accuracy and reliability of the power supply system are of key importance, such as battery charger, computer monitors, and telecom applications. The adjustable synchronous rectification of the LT3758IDD#TRPBF ensures high efficiency over a wide input voltage range. It is designed to minimize losses in power systems, and support short-circuit and overload protection.

The LT3758IDD#TRPBF has a synchronous rectification feature which simplifies the application of the switching converter. This synchronous rectification allows the device to switch off one of the two outputs during the off times of the switching cycle, so as to minimize total losses. With the LT3758IDD#TRPBF, the external MOSFETs can be controlled independently of the output voltage regulation. This feature, combined with the low internal resistance of the device, helps to reduce system cost and lower power loss.
