Overview
The LT1372HVCS8#PBF is a high-voltage switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 30 V and delivers a switch current of 1.5 A. The device supports multiple topologies including Boost, Buck, Cuk, Flyback, Forward, and Inverting configurations. It features a fixed switching frequency of 500 kHz and provides an adjustable output voltage starting from 1.245 V. The component is housed in an 8-lead SOIC package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Supports versatile DC/DC conversion topologies such as boost, buck, flyback, and SEPIC within a single monolithic IC.
- Enables compact system designs through high-frequency switching that allows the use of small external inductors.
- Provides flexible power management with adjustable output voltage and positive or negative output configuration options.
Applications
- Space-constrained portable electronic systems requiring efficient step-up or step-down regulation
- Battery-powered equipment utilizing single-cell alkaline or lithium-ion sources
- Industrial control modules requiring isolated or non-isolated power conversion
Procurement Notes
Verify the specific suffix CS8 corresponds to the commercial temperature grade and SOIC-8 package variant. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the ordering part number matches the required lead-free specifications for your manufacturing process.
Selection Notes
Select this component when a wide input voltage range up to 30 V is required alongside high efficiency. It is suitable for applications needing multiple topology flexibility without changing the core controller. Consider thermal performance in the SOIC-8 package for high-current continuous operation scenarios.
Part Context
This part belongs to the LT1372 family of high-efficiency switching regulators. It shares functional similarities with the LT1372IS8#PBF but differs in package type and potentially temperature rating. The HV designation indicates enhanced input voltage handling capabilities compared to standard variants.
Replacement Considerations
LT1372IS8#PBF offers identical electrical functionality in an SOIC-8 package. LT1372HVIN8#PBF provides the same performance in a PDIP-8 through-hole package. Verify pinout compatibility and thermal characteristics when substituting.
