products)
Author
Power Integrations Applications Dept.
Doc Num. EPR-000014
Date
22 Feb 2002
Revision
1.3
Features
• Cost effective (minimum parts count and single sided PC board)
• Low Cost EF12.6 transformer (132 kHz operation)
• Compact design: 2.0” x 1.2” x 0.75”
• No-load consumption < 250mW (230 V_AC)
• Auto-restart function limits overload output power
• Short circuit protected
• Built-in circuitry practically eliminates audible noise (standard varnished transformer)
• ON/OFF control allows simple Zener reference and eliminates the need for loop compensation
• No-load regulation achieved without preload resistor
• Low EMI due to frequency jittering: meets CISPR22B with output capacitively grounded
• Optional under-voltage detect eliminates power-up glitches
• Hysteretic thermal shutdown: Protects power supply and automatically recovers when fault is
removed
