Overview
The LT1372CN8#PBF is a monolithic high-frequency switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7 V to 30 V and delivers an adjustable output voltage up to 42 V with a switch current capacity of 1.5 A. The device functions at a fixed switching frequency of 500 kHz and maintains a typical operating supply current of 4 mA. It supports multiple topologies including boost, buck, flyback, forward, inverting, Cuk, and SEPIC configurations.
Feature Summary
- Integrates a 1.5 A high-efficiency power switch with complete oscillator, control, and protection circuitry on a single die.
- Supports versatile DC-DC conversion topologies including boost, buck, flyback, forward, inverting, Cuk, and SEPIC.
- Features a shutdown pin for low-power standby operation and accommodates wide input voltage ranges.
Applications
- Lithium-ion battery powered systems requiring step-up or SEPIC conversion
- General-purpose isolated and non-isolated DC-DC converter designs
- Space-constrained applications utilizing standard surface-mount or through-hole packaging
Procurement Notes
Verify the specific suffix CN8#PBF corresponds to the PDIP-8 package when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the ordering part number matches the required temperature grade and package style for your assembly process.
Selection Notes
Select this component for designs requiring a single-chip solution for multiple standard switching topologies. The integrated 1.5 A switch eliminates the need for external pass transistors. Consider the 500 kHz switching frequency for balancing component size against electromagnetic interference requirements.
Part Context
This part belongs to the LT1372 family of high-frequency switching regulators. It shares functional similarities with variants like the LT1372CS8 and LT1372HVCN8#PBF, differing primarily in package type and thermal characteristics. The CN8#PBF designation specifically indicates the through-hole PDIP-8 configuration.
