DC DC Switching Controllers Procurement Notes
Verify the specific suffix HFE against the manufacturer's official datasheet to confirm the extended temperature rating and package details. Ensure the ordering information matches the exact part number requirements for your design specifications. Cross-reference the lead time and availability status directly with authorized distributors as stock levels fluctuate.
DC DC Switching Controllers Selection Notes
Select this controller when designing multiphase boost converters that require operation up to 150°C ambient temperature. The 300 kHz fixed frequency simplifies filter component selection compared to adjustable variants. Consider the TSSOP-EP-24 package for thermal dissipation needs and ensure the external MOSFET gate drive requirements align with the 20 mA output capability.
DC DC Switching Controllers Part Context
This component belongs to the LTC3862 family of high-voltage, multiphase boost controllers. It is designed to drive external N-channel MOSFETs in synchronous or asynchronous configurations. The device is often evaluated using demonstration circuits such as the DC2006A-B series for high-power applications.
DC DC Switching Controllers Replacement Considerations
The LTC3862EFE-2#PBF serves as a public confirmed substitute within the same product family, offering identical electrical performance but with a limited operating temperature range of -40°C to +85°C instead of the extended range.
