5, size: 64*32mm
This chip is dedicated for small power switching power supply control chip,Can realize12WPower scheme within (e.g., 5V2A, 12V1A),
canIt is widely used in power adapter, LED power supply, induction cooker, air conditioner, DVD and other small household appliances.
This chipThe built-in overcurrent protection circuit, overload protection circuit, output short circuit protection, temperature protection circuit and optocoupler failure protection circuit.
RCC principle relative to discrete devicesSwitching power supply or RC resistance capacitance step-down scheme,This chip has a stronger load drive capability, more secure electrical protection and isolation performance!
The transformer is also very simple, no additional winding, single group can!
The price (only about 5 hair) is awesome! It has a high market share at present!
