DC DC Switching Controllers Procurement Notes

Verify the specific suffix MPS6 against official Analog Devices documentation to confirm the military-grade temperature rating and package variant. Ensure compatibility with your PCB footprint for the TSOT-23-6 package. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

DC DC Switching Controllers Selection Notes

Select this controller when designing flyback converters requiring a wide input voltage range up to 75 V. The fixed 5 V output simplifies transformer design for standard logic levels. Consider the -55°C to +150°C operating range for harsh environments. Verify that the external N-channel MOSFETs can handle the required peak currents at the 200 kHz switching frequency.

DC DC Switching Controllers Part Context

This part belongs to the LTC3803 family of flyback controllers from Analog Devices. The series offers various temperature grades and package options. The MPS6 suffix typically denotes a specific military or extended grade variant within the ThinSOT-23-6 packaging family, distinguishing it from commercial IS6 or industrial ES6 versions.

DC DC Switching Controllers Replacement Considerations

Direct replacements include other LTC3803 variants such as LTC3803IS6-5 or LTC3803ES6-5, provided the temperature range requirements are met. Verify pinout compatibility and electrical parameters before substitution.
