Heng Jiaxing AO3401

1.5PF SOT23-6 Low Capacitance 5V Breakdown Voltage 6V SRV05

Summary:

A 2.4 W constant voltage / constant current (CV / CC) universal input charger power supply circuit diagram, the design uses Power Integrations LinkSwitch series LNK-603DG. This design is suitable for cordless phone base chargers or any similar application with constant voltage/constant current characteristics.

design feature

• A revolutionary control concept that enables a low component count and low cost solution
• Primary side control eliminates secondary side controllers and optocouplers
• Constant pressure (CV) accuracy: ± 5%
• Constant current (CC) accuracy: ±10%
• Overheat protection with hysteresis recovery ensures PCB temperature is safe under all conditions
• Automatic restart: output short circuit and open loop protection
• Extremely energy efficient
• Average efficiency over the entire load range: 75% (ENERGY STAR 2.0 requires 67%)
• No-load input energy consumption: <30 mW at 230 VAC input
• Ultra-low leakage current: <5 μA at 265 VAC input (no Y capacitor required)
• Easily meet the following standard requirements:
• Class B Conducted EMI Requirements for EN55022 and CISPR-22 (EMI Margin >10 dBμV)
• IEC 61000-4-5 Level 3 AC Input Surge (10 kV Common Mode)
• IEC 61000-4-2 Electrostatic discharge immunity (range ±15 kV)
