AC DC Converters, Offline Switchers Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS certification status as per manufacturer documentation. Confirm the specific revision level matches design requirements. Ensure the SOIC-16 package dimensions align with PCB layout constraints. Validate that the operating temperature range meets environmental specifications. Cross-reference datasheet electrical characteristics against system performance needs before finalizing procurement.

AC DC Converters, Offline Switchers Selection Notes

Select this component when high-speed PWM control is required for single-output switching regulators. It is suitable for designs needing flexible topology support such as flyback or forward converters. Consider its 2 A drive capability for direct gate driving of external MOSFETs. Evaluate the 1 MHz frequency limit against efficiency and size trade-offs. Ensure the 10 V to 30 V input range covers the application's supply variations.
