The LT1074HVCT#PBF is a 5A monolithic bipolar switching regulator manufactured by LTC. It is designed for step-down (buck) converter applications and requires minimal external components for operation.
Key features include a 5A onboard switch, allowing operation with input voltages up to 60V. The device operates at a switching frequency of 100kHz and has a quiescent current of 8.5mA. It supports a buck converter output voltage range of 2.5V to 50V and can achieve up to 10A output current in a tapped-inductor configuration.
The regulator incorporates on-chip pulse-by-pulse current limiting for protection against output overloads or shorts. Its design allows for use in positive-to-negative conversion and negative boost converter configurations. The LT1074HVCT#PBF is available in low-cost TO-220 or DD packages, with a 7-lead TO-220 package also available for adjustable current limit down to zero. Micropower shutdown can also be programmed.
This switching regulator is suitable for various power supply designs requiring efficient voltage conversion. Its robust features and wide input voltage range make it a versatile component for demanding applications.
