Overview
The LT1076CT7#PBF is a monolithic switching voltage regulator from Analog Devices Inc., housed in a TO-220-7 package. It operates as a Buck, Boost, or Flyback converter with an adjustable output range of 2.5V to 40V. The device supports a maximum switch current of 2A and accepts input voltages up to 45V. Key electrical parameters include a quiescent current of 8.5 mA and a fixed switching frequency of 100 kHz. It functions within an operating temperature range of 0°C to +70°C.
Feature Summary
- Supports multiple topologies including step-down (Buck), step-up (Boost), and flyback configurations.
- Provides positive or negative adjustable output voltage control.
- Integrates internal power switch for efficient DC-DC conversion.
Applications
- General-purpose DC-DC power supply design
- Battery-powered equipment requiring voltage regulation
- Industrial control systems needing isolated or non-isolated power rails
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the TO-220-7 package variant matches thermal requirements. Ensure the supplier provides official datasheets for the LT1076 series to validate pinout and electrical limits against application needs.
Selection Notes
Select this component for applications requiring high efficiency and flexible topology options. The 2A switch current capability suits moderate load requirements. Consider the 100 kHz switching frequency for balancing component size and noise. Verify input voltage ranges do not exceed the 45V maximum limit.
Part Context
This part belongs to the LT1076 family of switching regulators, known for robust performance in various power management roles. It serves as a versatile solution for converting unregulated power sources into stable regulated outputs across different industrial and commercial sectors.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer updated packaging or extended temperature ranges if required by the specific application environment.
