Overview
The LT1076HVCT#PBF is a high-voltage monolithic bipolar switching regulator manufactured by Analog Devices Inc. It operates in a buck topology with a fixed 5V output and supports an input voltage range of 8V to 60V. The device delivers up to 1.6A of output current with a switching frequency of 100kHz. It features integrated power switching, oscillator, control circuitry, and current limit components. Packaged in a TO-220-5 through-hole case, it functions within a temperature range of 0°C to +70°C.
Feature Summary
- Integrates power switch, oscillator, control circuitry, and current limit components on a single chip
- Supports versatile topologies including positive-to-negative conversion, negative boost, and flyback configurations
- Switch output specified to swing 40V below ground for tapped-inductor applications
Applications
- Tapped-inductor buck converters
- Positive-to-negative converters
- Negative boost converters
- Flyback converters
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS status. Confirm the HV designation aligns with the required high-voltage input specifications. Ensure the TO-220-5 package matches the thermal and mechanical constraints of the target PCB layout. Cross-reference the fixed 5V output against system requirements.
Selection Notes
Select this component when a high-input voltage buck converter is required with integrated switching capabilities. The fixed 5V output simplifies design compared to adjustable variants. Consider the TO-220-5 package for through-hole mounting needs. Verify that the 1.6A current rating meets load demands without excessive thermal management.
Part Context
This part belongs to the LT1076 series of high-voltage switching regulators. It shares core architecture with other LT1076 variants but differs in input voltage handling and output configuration. The HV variant specifically addresses higher input voltage requirements while maintaining the series' compact integration of control and power stages.
Replacement Considerations
LT1076HVIT#PBF is listed as a parameter equivalent substitute.
