DC DC Switching Controllers Procurement Notes
Verify the specific suffix 'PW' corresponds to the TSSOP-16 package variant when sourcing. Confirm that the commercial temperature rating aligns with system requirements. Ensure compatibility with existing PCB footprints designed for this specific package type before finalizing procurement orders.
DC DC Switching Controllers Selection Notes
Select this component for designs requiring high switching frequencies up to 1 MHz with reduced startup current. It serves as a direct pin-compatible upgrade to UC3846 series devices, offering improved performance while maintaining familiar architecture. Ideal for applications needing dual outputs and precise current mode control.
DC DC Switching Controllers Part Context
The UCC3806 is part of Texas Instruments' BiCMOS PWM controller family, designed as an advanced version of the popular UC3846 series. It retains the same block diagram and pinout but delivers higher switching frequency capabilities and significantly lower internal bias currents. This lineage ensures ease of transition for engineers familiar with legacy controllers.
DC DC Switching Controllers Replacement Considerations
The UC3846DW is a documented substitute with similar functionality but lower frequency limits.
