DC DC Switching Controllers Procurement Notes
Verify the specific suffix '2' indicates the correct supply voltage window and temperature grade. Confirm the TSSOP-8 package variant matches the design requirements. Ensure RoHS compliance documentation aligns with project specifications before finalizing procurement orders.
DC DC Switching Controllers Selection Notes
Select this component for applications requiring a 1 MHz switching frequency and BiCMOS technology. It is suitable where a 8.3 V to 12 V supply range is available. Consider the 8-TSSOP package constraints for PCB layout. Evaluate thermal performance within the 0°C to 70°C operational envelope.
DC DC Switching Controllers Part Context
This part belongs to the UCC3813 family of low-power current mode PWM controllers. It shares functional similarities with other variants like the UCC3813PW-0G4 but differs in supply voltage thresholds and temperature ratings. The family targets cost-sensitive, high-efficiency power management solutions.
DC DC Switching Controllers Replacement Considerations
Direct substitutes include UCC3813PW-0G4 and UCC3813N-2. Verify pin compatibility and electrical parameter alignment, specifically UVLO levels and operating temperature ranges, before implementing any cross-replacement.
