LT1107CS8-5#PBF

Overview

The LT1107CS8-5#PBF is a micropower DC/DC converter manufactured by Analog Devices Inc., housed in an SOIC-8 surface-mount package. It operates as both a buck and boost regulator with a fixed 5 V output capable of delivering up to 800 mA. The device accepts an input voltage range from 2 V to 30 V. Key electrical specifications include a quiescent current of 360 uA, a switching frequency of 63 kHz, and operation within a temperature range of 0°C to +70°C.

Feature Summary

Supports versatile buck and boost topologies for flexible power conversion
Delivers high output current capability suitable for logic supply applications
Maintains low static current consumption for battery-powered efficiency

Applications

Portable computer logic power supplies
Battery-operated systems requiring step-up or step-down regulation
General-purpose micropower DC/DC conversion circuits

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the fixed 5V output aligns with your load needs, as adjustable variants exist within the same series. Check manufacturer documentation for any recent product change notices affecting pinout or thermal characteristics.

Selection Notes

Choose this component when a fixed 5V output is required alongside high current drive capabilities. The wide input voltage range supports various single-cell or multi-cell battery configurations. Consider the 63 kHz switching frequency for balancing component size against noise sensitivity. Verify that the absence of a shutdown pin meets your system's power management strategy.

Part Context

This part belongs to the LT1107 series of micropower DC/DC converters. It shares the SOIC-8 package form factor with other devices in the family but differs in internal configuration to provide a fixed 5V output. The series is designed for applications prioritizing space savings and power efficiency in portable electronics.
