Procurement Notes

Verify the specific suffix P8T1G against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required switching frequency range and input voltage parameters before integration. Cross-reference the RoHS status and environmental compliance data provided in the manufacturer's datasheet to meet regulatory requirements for your target market.

Selection Notes

Select this component when a boost topology is required for applications operating between 1.8V and 6V. Consider the 8-SON package size for space-constrained designs. Verify that the required switching frequency falls within the 257.4kHz to 1.134MHz range and that the system can accommodate the necessary external components for frequency setting and protection circuits.

Part Context

This part belongs to the S-8338 series of high-frequency PWM control switching regulator controllers from ABLIC. The series is characterized by its ability to operate at low minimum voltages, making it distinct from standard regulators that require higher input thresholds. It shares architectural similarities with the S-8337 series but offers specific performance characteristics tailored for efficient step-up conversion in portable electronics.
