LT1680CN#PBF

Overview

The LT1680CN#PBF is a high power, current mode switching power supply controller optimized for boost topologies. It drives an N-channel MOSFET switch to provide DC/DC step-up conversion. The device operates with an input voltage range of 4 V to 60 V and delivers an output current of 700 mA. It features a fixed switching frequency of 200 kHz and a low static current of 150 uA. The unit is housed in a 16-PDIP package and supports operation within a temperature range of 0°C to +70°C.

Feature Summary

• Current mode control architecture optimized for boost applications
• Integrated shutdown capability for power management
• High input voltage tolerance up to 60 V

Applications

• Industrial power systems
• Battery-powered equipment requiring voltage step-up
• General-purpose DC/DC step-up converter designs

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards before procurement. Confirm that the PDIP-16 through-hole package matches the target PCB footprint. Ensure the supplier provides valid traceability documentation for Analog Devices Inc. components to guarantee authenticity.

Selection Notes

Select this component when a robust boost controller is required for high-power applications. The wide input voltage range suits diverse source conditions. Current mode control offers improved transient response compared to voltage mode alternatives. Verify external component ratings align with the 700 mA output specification.

Part Context

This part belongs to the LT1680 series of switching regulators manufactured by Analog Devices Inc. It serves as a dedicated controller rather than a complete integrated regulator, requiring external MOSFETs and passive components. The series is designed for efficiency and reliability in industrial environments.

Replacement Considerations

LT1680CSW#PBF is a documented surface-mount variant of the same functional core.
