LT3782AIFE

The LT3782AIFE is a multifunction DC-DC controller designed for use in applications where high efficiency and precise regulation of output voltage is required. The LT3782AIFE offers current mode control and includes protection features such as over current, over voltage, open circuit and short circuit protection. It is a fully featured device with PWM and Sine Wave modulation architectures, adjustable soft start and frequency hopping to provide robust system operation.

The LT3782AIFE is adjustable from 4.75V to 40V and the adjustable current limit capability is adjustable from 0A to 1.5A. It is ideal for use in applications such as secondary side regulation when used in a buck-boost topology, or in multiple output systems for precise voltage regulation for higher power requirements. Other features include adjustable switching frequency up to 1MHz, synchronous rectification for higher efficiency and adjustable operating frequencies for cool operation.

The LT3782AIFE\'s switching frequency can be adjusted from 300kHz up to 1MHz depending on the application, and an analog reference input for current control. Also, the switching frequency and deadtime of the control ramp-up and ramp-down is settable to give great flexibility in low voltage, high power applications.

The LT3782AIFE is designed to operate with MOSFETs and can be used in a synchronous buck, boost, buck-boost, or dual isolated buck-boost applications. The device has adjustable soft-start and frequency hopping capabilities to provide robust system operation and higher efficiency. The LT3782AIFE includes a low voltage protection feature that allows it to shut off at a predetermined voltage, preventing possible harm to the system.

The LT3782AIFE is a highly integrated and compact handheld device specifically designed to provide regulated power with maximum efficiency and performance in the most demanding applications. The LT3782AIFE provides MOSFET gate drivers, current sensing, error amplifier and protection features designed to ensure robust system operation and high efficiency. The LT3782AIFE is ideal for use in applications requiring tight voltage regulation such as automotive, industrial, aviation, medical and many other applications.

The LT3782AIFE works by quickly pulsing the switch pair to cause the current sensing resistor to very quickly change the output voltage. This occurs by the output voltage being clamped at the current limit set point, but this is also dependent on the output current level. As such, the LT3782AIFE is able to provide precise voltage outputs over a wide range of loading conditions.

In summary, the LT3782AIFE is a highly integrated DC-DC controller designed for applications where precise output voltage regulation is required. It offers current mode control, adjustable soft start, and frequency hopping to provide robust system operation. Furthermore, it is highly efficient and has adjustable current limit capability and adjustable switching frequency up to 1MHz for optimal performance.
