Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's official datasheet to confirm compliance with RoHS directives and lead-free manufacturing standards. Confirm that the POWeDIP-20 package matches your PCB footprint requirements. Ensure the fixed 150 ns dead time aligns with your resonant tank design parameters before finalizing procurement.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when designing LLC resonant topologies requiring integrated half-bridge switching with minimal external gate drive complexity. The fixed dead time simplifies timing calculations compared to adjustable variants. Ensure the 600 V breakdown voltage suits the bus voltage requirements of the target application. Verify compatibility with synchronous rectification controllers like the HiperLCS2-SR for optimal system performance.

Full Half-Bridge (H Bridge) Drivers Part Context

The LCS7269Z belongs to the HiperLCS-2 chipset family from Power Integrations, which simplifies the design of LLC resonant power converters. This series includes primary-side devices like the LCS726x and secondary-side synchronous rectification controllers. The chipset is engineered to reduce component count and improve reliability in high-power AC-DC conversion applications.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

The LCS7268Z is part of the same HiperLCS-2 family but features adjustable dead times ranging from approximately 90 to 500 ns, unlike the fixed 150 ns of the LCS7269Z. Designers must verify if the adjustable timing capability is required or if the fixed timing of the LCS7269Z is sufficient for their specific resonant frequency and efficiency targets.
