Overview
The LT1372HVCN8#PBF is a monolithic high-frequency switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 30 V and supports a maximum switch current of 1.5 A. The device features adjustable output voltage starting from 1.245 V, with a fixed switching frequency of 500 kHz. It is housed in an 8-pin PDIP package (0.300 inch width) designed for through-hole mounting. The component functions across a temperature range of 0°C to +125°C junction temperature.
Feature Summary
- Supports multiple standard switching topologies including boost, buck, Cuk, flyback, forward, and inverting configurations.
- Integrates a high-efficiency 1.5 A power switch along with complete oscillator, control, and protection circuitry on the die.
Applications
- DC-DC conversion circuits utilizing Cuk topology
- Boost converter designs for voltage step-up applications
- Buck converter implementations for voltage step-down requirements
Procurement Notes
Verify the specific suffix HVCN8 against official Analog Devices documentation to confirm the high-voltage variant specifications and PDIP-8 package details. Ensure compatibility with through-hole assembly processes. Cross-reference the manufacturer part number LT1372HVCN8#PBF with authorized distributors to validate current availability status and lead times prior to procurement planning.
Selection Notes
Select this component when a through-hole solution is required for high-frequency switching applications. The 1.5 A switch current capability suits moderate power levels. Verify that the 0°C to 125°C operating range meets thermal requirements. Consider the 500 kHz fixed frequency for passive component sizing compared to variable frequency alternatives.
Part Context
This part belongs to the LT1372 series of high-frequency switching regulators. The series includes variants such as LT1372IS8#PBF in SOIC-8 packages. The HVCN8 designation indicates a specific pin-compatible or feature-enhanced version within the family, distinguished by its through-hole packaging and potentially extended voltage ratings compared to standard versions.
Replacement Considerations
LT1372IN8#PBF offers identical electrical performance in a PDIP-8 package. LT1372IS8#PBF provides the same functionality in an 8-SOIC surface-mount package. Verify pinout compatibility and thermal management requirements when substituting between package types.
