0603 white

Summary:

The non-isolated flyback converter design shown in the figure uses the TNY279 device to provide two output voltages: -5 V/2A- and 12 V/250 mA (continuous), 600 mA (peak).

design feature

• Low cost and low component count
• No impedance from the neutral to the output RTN, ideal for driving triacs
• No-load power consumption <150 mW at 230 VAC AC input
• Both outputs have good cross regulation
• The highest ambient temperature reaches 70 °C
• Compliant with CISPR-22 Class B/EN55022 B EMI limits, no need to input common mode chokes
