LT1076CT-5#06PBF belongs to the linear technology\'s family of DC DC Switching Regulators. Designed for applications like parallel regulators, hot swap controllers and pre-regulation, steps down the input voltage to a user-defined output. It has external sense connections with high side and low side current sensing, which includes voltage-mode feedback control and basic current-mode control capabilities.

The LT1076CT-5#06PBF includes sixteen possible combinations depending on the control pin-strapping, allowing us to get the ideal mode of operation for different applications. It offers advanced features like integrated voltage-mode control, adjustable blanking and soft-start, as well as a wide operating temperature range.

Regarding its application field, the LT1076CT-5#06PBF is suitable for a wide range of applications like solutions to provide power supply in multi-rail systems while its internal 2Ms minimum cycle-by-cycle current limit protect it from short circuit fault conditions. Also, since it is made with high-side and low-side current sensing capabilities, it can be used in hot swap applications, such as powering large, stored static power.

Concerning the device’s working principle, the LT1076CT-5#06PBF is a Current-Mode, synchronous step-down DC DC converter. It includes an internal Low-RDS(on) High-side MOSFET and Synchronous Low-side MOSFET that are driven at a fixed frequency (288kHz) by a current-mode PWM control. Its regulator circuit includes a comparator that compare an internal reference voltage and the voltage applied across a current sense resistor , producing a fixed off-time by leading edge modulation. The inductor behaves as a low-pass filter. The output is determined by the control loop with a PR (Peak Referencing) compensation network comprising of an internal transconductance amplifier and an external compensation capacitor.

LT1076CT-5#06PBF is an robust switching regulator made to power laser diode applications, LED lighting and other high-performance circuits that require tight regulation, high efficiency and advanced protection.
