Overview
The LT1370HVCR#TRPBF is a high-efficiency, high-frequency current mode switching regulator manufactured by Analog Devices Inc. It supports multiple topologies including Boost, Buck, Cuk, Flyback, Forward, and Inverting configurations. The device operates with an input voltage range of 2.7 V to 30 V and delivers a switch current of 6 A. It features a fixed switching frequency of 500 kHz and adjustable output voltage. The component is housed in a DDPAK-7 (TO-263-8) surface-mount package and functions within a temperature range of 0°C to +70°C.
Feature Summary
- Supports versatile power conversion topologies including buck, boost, flyback, and SEPIC configurations.
- Integrates a 500 kHz fixed-frequency current mode controller for efficient power management.
- Capable of delivering up to 6 A of switch current for high-power applications.
Applications
- Industrial power supply systems
- Telecommunications equipment
- Battery-powered devices requiring step-up or step-down regulation
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the HV variant rating matches the required input voltage specifications. Ensure the DDPAK-7 package footprint aligns with the target PCB design. Cross-reference the manufacturer's latest datasheet for any pinout or thermal pad modifications.
Selection Notes
Select this component for designs requiring a single IC to handle multiple converter topologies. The 6 A current capability suits moderate-to-high power loads. Consider the 500 kHz frequency for balancing component size and efficiency. Verify that the operating temperature range meets the environmental requirements of the final assembly.
Part Context
This part belongs to the LT1370 family of high-frequency switching regulators. It shares core control architecture with variants like the LT1370CR but differs in voltage ratings and packaging. The HV designation typically denotes higher voltage tolerance capabilities compared to standard versions.
Replacement Considerations
LT1370HVCR#PBF is a tube-packaged equivalent from the same series. LT1370HVIR#PBF offers similar electrical characteristics in a different surface-mount package variant.
