The LT1074HVIT#PBF is a high-performance switching regulator operated at up to 1.2 MHz. It can be used to provide regulated voltages from a wide range of input voltages common to automotive, telecom and industrial applications, from 4.5 to 40 V with an adjustable output range of 0.8 V to 28 V. The device efficiently provides up to 10 A of current and is ideal for powering low voltage microprocessors, video RAM and ASIC cores in either step-up or step-down configurations.

The LT1074HVIT#PBF uses high-performance switch-mode technology to ensure high power conversion (up to 97%) while minimizing power losses to ensure that the supplied power reliably starts up the load. The switch is driven by an integrated oscillator, which is adjustable between 400 kHz and 1.2 MHz and can be synchronized to external clock signals. This allows the device to minimize the size of external components.

The LT1074HVIT#PBF also features an on-chip soft-start and current limiting circuit as well as a thermal shutdown circuit to ensure reliable performance in sustained load conditions. Additionally, it includes a power good output signal that indicates when the output of the regulator has reached the programmed voltage to provide an additional layer of protection for the system.

The LT1074HVIT#PBF is available in an 8-pin HVIT (high voltage isolated transistor) package, which features excellent thermal performance, making it suitable for use in high-temperature environments such as automotive, telecom and industrial applications. Furthermore, its pin-compatible package allows it to easily replace existing voltage regulators without having to redesign the entire system.

In summary, the LT1074HVIT#PBF is a high-performance, high-efficiency switching regulator with an excellent thermal performance profile, making it ideal for automotive, telecom and industrial applications. Its integrated soft-start and current limiting circuit as well as power good output signal make it an ideal choice for a wide range of applications including powering low voltage microprocessors, video RAM and ASIC cores.
