Overview
The LT1370IT7#PBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 30V and supports adjustable output voltages from 1.245V up to 35V. The device delivers a switch current of 6A at a fixed switching frequency of 500kHz. It features a TO-220-7 package for through-hole mounting and functions as a buck, boost, Cuk, flyback, forward, or SEPIC converter. The component is rated for an operating temperature range of 0°C to 70°C.
Feature Summary
- Supports multiple standard switching topologies including buck, boost, Cuk, flyback, forward, and inverting configurations.
- Integrates a high-current, high-efficiency power switch with complete oscillator, control, and protection circuitry on the die.
- Provides adjustable output voltage capability with positive or negative output configuration options.
Applications
- LCD contrast power supplies
- External current limiter circuits
- Driving high-voltage NPN transistors
Procurement Notes
Verify the specific suffix IT7 against official Analog Devices documentation to confirm the tape-and-reel packaging variant versus tube packaging. Ensure the order matches the exact part number LT1370IT7#PBF to avoid confusion with other LT1370 family members. Confirm RoHS compliance status via the manufacturer's material declaration before finalizing procurement.
Selection Notes
Select this component when a single IC must support various DC-DC conversion topologies without external driver complexity. The 6A switch current rating suits applications requiring moderate to high power density. Consider the TO-220-7 package for thermal management needs in through-hole designs. Verify that the 500kHz switching frequency aligns with electromagnetic interference constraints and passive component size requirements.
Part Context
The LT1370 belongs to Analog Devices' line of high-power switching regulators designed for versatility. Unlike fixed-frequency controllers, it integrates the power switch, allowing simplified design for complex topologies. The IT7 suffix typically denotes a specific reel quantity and packaging format within the broader LT1370 product family, distinguishing it from tube-packaged variants like the LT1370CT7#PBF.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Evaluate pin-compatible alternatives only if official cross-reference documentation from Analog Devices confirms functional equivalence for all specified topologies and electrical parameters.
