The LT1076HVCT#PBF is a synchronous DC/DC buck converter IC which offers incredible efficiency, ultra low noise and fast transient response in a miniature 4x4mm QFN package. It provides flexible output capability and intelligent power control, featuring a combined PWM/PFM control mode that allows seamless conversion between very low power (100µA) and high power operation. This IC is widely used in low-input, high-output applications such as modem power supplies where low noise, high efficiency and small size are required.

The working principle of the LT1076HVCT#PBF is based on a synchronous buck converter circuit, which regulators the input voltage to an output voltage. The circuit consists of an inductor, an output capacitor, and an internal high-side and low-side switch. The inductor creates a magnetic field with the current, which is then released through the output capacitor when the internal switch is opened to regulate the voltage. This continuous process, known as switching, is what regulates the output voltage according to the input voltage.

The LT1076HVCT#PBF is primarily used in portable devices, and other applications where efficient voltage regulation is needed. It can be used to power microcontrollers, application processors, RF transceivers, and high-accuracy communication circuits. It is also suitable for a wide variety of industrial and laboratory applications due to its flexibility and accuracy. It features an adjustable switching frequency, selectable to range between 300kHz to 1.25MHz.

The LT1076HVCT#PBF offers superior regulation accuracy, fast transient response and low noise operation up to high frequencies (100MHz). It also provides a wide input voltage range of 2.7V to 48V, meaning it can be used in a variety of situations. The IC can be easily configured using a single resistor to generate any output voltage from 0.6V to 5V, and it can deliver up to 10A of output current. It is also designed for high efficiency, with power losses as low as 4mW for lightweight regulated power supplies.

The LT1076HVCT#PBF also features an Advanced Gate Drive (AGD) circuit, which enhances the efficiency of the switching circuit by providing optimal switching performance with minimal power loss. It also has integrated thermal protection, short circuit protection, and current limit protection, making it an ideal choice for rugged and reliable applications. In addition, the IC can be easily configured using its external components, meaning that it can be integrated into existing designs with minimal difficulty.

In conclusion, the LT1076HVCT#PBF is an incredibly efficient, low-noise and highly-accurate DC/DC buck converter IC, which is suitable for a range of demanding applications. It features a wide input voltage range of 2.7-48V, adjustable switching frequency and an advanced gate drive circuit which reduces power losses. It can be easily configured using a single resistor and its integrated protection features make it an ideal choice for rugged and reliable applications.
