Overview
The LT1680ISW#PBF is a high-power, current-mode switching power supply controller from Analog Devices, optimized for boost topologies. It operates with a supply voltage range of 4 V to 60 V and provides a single output. The device features a maximum duty cycle of 90% and a fixed switching frequency of 200 kHz. It is housed in a 16-pin SOIC W package.
Feature Summary
- Optimized for high-power boost converter applications
- Current-mode control architecture for stable operation
- Capable of driving N-channel MOSFET switches directly
Applications
- DC/DC step-up power supplies
- Industrial power conversion systems
- Battery-powered equipment requiring voltage boosting
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the 16-SOIC package dimensions match your PCB footprint requirements. Ensure the input voltage range aligns with your system's 4V to 60V specification before procurement.
Selection Notes
Select this component for applications requiring robust boost topology control within a wide input voltage range. The current-mode architecture suits designs needing precise regulation. Consider the 200kHz frequency for balancing efficiency and component size against higher-frequency alternatives.
Part Context
This part belongs to the LT1680 series of DC/DC controllers. It is designed by Analog Devices Inc. as a specialized solution for high-power boost converters. The ISW designation specifies the industrial temperature range and SOIC W package variant.
Replacement Considerations
Check Analog Devices documentation for direct pin-compatible upgrades or functional equivalents within the LT1680 family. Verify that any substitute maintains the 4V-60V input range and 200kHz switching frequency.
