LT1507IN8#PBF

Overview

The LT1507IN8#PBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates in a fixed mono buck mode with a switching frequency of 500 kHz. The device accepts an input voltage range from 4 V to 15 V and provides an adjustable output voltage. It supports a maximum output current of 1.5 A through a single output channel. Key electrical parameters include a static current of 4 mA and a working supply current of 3.8 mA. The component is housed in a PDIP-8 package designed for through-hole installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates a complete buck converter topology including internal power switch, oscillator, and error amplifier
Supports shutdown functionality for power management applications
Designed for high efficiency operation at a fixed 500 kHz switching frequency

Applications

Battery-powered equipment requiring efficient voltage regulation
Post-regulation stages for bus distribution systems
General-purpose DC/DC conversion in industrial control modules

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards before integration. Confirm that the PDIP-8 through-hole package aligns with the target PCB footprint and assembly process. Check current availability status as limited supply conditions may apply to this component series.

Selection Notes

Select this part when a through-hole solution is required for a 1.5 A buck converter application. Ensure the input voltage does not exceed 15 V and the load current remains within the 1.5 A limit. Consider thermal dissipation requirements for the PDIP-8 package under continuous load conditions.

Part Context

This component belongs to the LT1507 family of monolithic step-down switching regulators. It serves as a cost-effective alternative to linear regulators in applications where higher efficiency and lower heat dissipation are critical. The device simplifies design by integrating most external components necessary for buck conversion.
