DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the part number matches the exact electrical specifications required for your design, as variations exist within the LTC3835 family. Ensure compatibility with your PCB footprint, which is SSOP-16 for this variant. Cross-reference with official Analog Devices documentation to validate lead times and availability status directly with authorized distributors.

DC DC Switching Controllers Selection Notes

Select this controller when driving external N-channel MOSFETs is preferred for thermal management or current handling requirements exceeding integrated solutions. The 650kHz phase-lockable frequency allows synchronization with other converters to minimize system noise. Consider the 80µA quiescent current if battery life or standby power efficiency is critical. Ensure the application voltage does not exceed the 36V maximum input rating.

DC DC Switching Controllers Part Context

This component belongs to the LTC3835-1 series of low IQ synchronous buck controllers. It is distinct from the LTC3831 and LTC3838 series, which offer different current capabilities and pin configurations. The IGN-1 designation specifies the industrial temperature grade and SSOP package type. It serves as a flexible building block for custom power supply designs requiring precise control over external power stages.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other parts within the LTC3835 family, such as the LTC3835EGN-1#TR, noting that package and reel variations may differ. Verify that any replacement maintains the same 4V-36V input range and 650kHz max frequency. Check for identical SSOP-16 pinouts to ensure board compatibility without redesign.
