Summary:

The TinySwitch-PK multi-output power supply delivers 17.7 W of continuous output power and 29.7 W of peak power. Ideal applications include air conditioning and other applications that require peak power. Two electrically isolated 16 V outputs drive the IGBTs in the half-bridge topology. The 12 V output is used to drive the compressor evaporating fan, while the 5 V output is used to power the microprocessor. The 5 V and 12 V outputs are non-isolated from the AC input.

design feature

• Multiple output power supply
• Works within the universal input voltage range, so a single design can be applied globally
• Extremely energy efficient
• Low no-load power consumption (<160 mW at 265 V AC input)
• Meets CEC 2008/Energy Star requirements for efficiency in the on-load mode (requires 74.9%, up to 80%)
• Thermal performance
• High working temperature (TAMB = 85 oC)
• Accurate hysteresis thermal shutdown protection
• Compliant with CISPR-22/EN55022B conducted EMI limits, EMI margin >10 dBmV.
• Automatic restart function allows unlimited short-circuit output
