• Features programmable line undervoltage detection to prevent power on/off glitches.
• Utilizes frequency jittering to dramatically reduce electromagnetic interference emissions.

AC DC Converters, Offline Switchers Applications

• Cell-phone chargers
• PC standby power supplies
• Low-power offline AC/DC converters

AC DC Converters, Offline Switchers Procurement Notes

Verify the Not Recommended for New Design (NRND) status before implementation, as this indicates potential obsolescence risks. Confirm that the SMD-8B package matches your PCB footprint requirements. Ensure compliance with RoHS3 specifications and check moisture sensitivity level (MSL 4) handling procedures during assembly. Validate that the 132 kHz switching frequency aligns with your EMI filter design constraints.

AC DC Converters, Offline Switchers Selection Notes

Select this component for applications requiring extremely low no-load consumption, specifically under 250 mW without a bias winding at 265 VAC input. It serves as a cost-effective replacement for bulky regulated linear supplies or discrete PWM solutions. Consider its simple ON/OFF control scheme which eliminates the need for complex loop compensation circuits in basic designs.

AC DC Converters, Offline Switchers Part Context

This part belongs to the TinySwitch-II series, representing an evolution from the earlier TinySwitch-I models like the TNY255. The series focuses on enhanced energy efficiency and system cost reduction through high integration. It offers better performance compared to Resonant Converters (RCC) and linear regulators while maintaining a minimal component count.
