Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm compliance with RoHS standards and material declarations. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision to validate all electrical parameters before finalizing procurement.
Selection Notes
Select this component when a compact solution is needed for driving white LEDs from a single-cell lithium battery or similar low-voltage source. The 1 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 50 mA current limit when determining the number of series-connected LEDs suitable for the application.
Part Context
This part belongs to the TPS6104x family of switch boost converters designed specifically for LED applications. It shares architectural similarities with other devices in the series but is distinguished by its specific current rating and packaging options. The DRBRG4 designation indicates a specific tape-and-reel packaging configuration compliant with environmental standards.
Replacement Considerations
Direct substitutes include the TPS61042DRBT and TPS61042DRBR. Verify pin compatibility and thermal performance when swapping between these variants. Ensure that any replacement maintains the required 1 MHz switching frequency and 28 V output capability.
