lt1074mk Description

Short technical summary and product information.

The LT1074MK is a versatile monolithic bipolar switching regulator from Linear Technology, primarily designed for step-down (buck) converter applications. It integrates the power switch, oscillator, control circuitry, and current limit components onto a single chip, requiring only a few external parts for operation.

Key electrical specifications include a 5A onboard switch capability for the LT1074 variant, with the LT1076 rated at 2A. The device operates with an input voltage range of 8V to 60V in buck configuration, and can function with as low as 5V in inverting and boost modes. It features a 100kHz switching frequency and a low quiescent current of 8.5mA. The output voltage range for buck conversion is from 2.5V to 50V. The LT1074 can also drive a tapped-inductor in buck mode for output currents up to 10A.

Designed for robustness, the LT1074MK includes on-chip pulse-by-pulse current limiting, making it resistant to output overloads or shorts. It utilizes a true analog multiplier in the feedback loop for improved dynamic behavior, responding almost instantaneously to input voltage fluctuations. The current limit is preset at 6.5A for the LT1074 and 2.6A for the LT1076, with a 7-pin TO-220 package option allowing for adjustable current limit down to zero. Micropower shutdown is also programmable.

The LT1074MK is available in low-cost TO-220 or DD packages. The TO-220 package is suitable for through-hole mounting.
