DC DC Switching Controllers Procurement Notes

Verify the specific package type against design requirements, as the TL1454 series includes both surface mount and through-hole variants. Confirm that the 'CN' suffix corresponds to the 16-PDIP package intended for your board layout. Ensure compatibility with the required input voltage range of 3.6 V to 20 V for your specific application circuit before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when a dual-channel controller supporting multiple topologies is required. The TL1454CN is suitable for designs needing synchronous rectification support and wide frequency adjustability. Consider the through-hole PDIP package if prototyping or specific mechanical constraints necessitate non-surface-mount integration. Verify thermal performance within the specified -20°C to +85°C operating range.

DC DC Switching Controllers Part Context

The TL1454CN belongs to the TL1454 family of dual-channel PWM controllers from Texas Instruments. This series is engineered for general-purpose DC-DC conversion applications requiring flexibility in topology selection. The CN designation specifically identifies the through-hole plastic dual-in-line package variant, distinguishing it from surface-mount options like the DW or DGK packages within the same functional family.

DC DC Switching Controllers Replacement Considerations

The TL1454ACNE4 is a verified lead-free replacement part number within the same product family, offering identical electrical characteristics and functionality while complying with RoHS standards.
