Overview
The LT1270ACT#PBF is a high-efficiency switching voltage regulator IC manufactured by Analog Devices Inc. It features an internal power switch rated for 10A and supports buck, boost, and flyback topologies. The device operates with a wide input voltage range from 3.5V to 30V and delivers a single adjustable output starting at 1.244V. Packaged in a TO-220-5 housing, it integrates self-protection mechanisms against overload conditions while maintaining low quiescent current consumption of 7mA.
Feature Summary
- Integrates a high-current internal power switch for efficient energy conversion
- Supports multiple converter topologies including buck, boost, and flyback configurations
- Includes built-in self-protection features to safeguard against overload events
Applications
- Buck converter circuits requiring high current handling
- Boost converter designs for voltage step-up applications
- Flyback power supply implementations
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the package type matches the TO-220-5 specification required for your thermal management design. Ensure the input voltage range aligns with your system's power source capabilities to prevent operational failure.
Selection Notes
Select this component when a robust internal switch capable of handling up to 10A is required without external discrete transistors. It is suitable for designs needing flexibility across buck, boost, or flyback architectures. Consider the wide input voltage range if operating in environments with varying supply levels.
Part Context
This part belongs to the LT1270 family of switching regulators designed for high-efficiency power conversion. It serves as a versatile solution for industrial and commercial power supplies where space savings and reduced external component count are critical design priorities.
Replacement Considerations
LT1270CT#PBF is a confirmed substitute within the same product family offering similar functionality.
