Description

Outline

The MM1540CF is an IC chip that acts as a secondary control on AC adaptors with an energy-saving mode. This intelligent function helps to greatly reduce the AC adaptor's power consumption by automatically switching to the energy-saving mode when charging is complete or when the set is unplugged. The IC also features a smaller size and requires fewer external components compared to the conventional MM1529.

Specifications and features

The following are the specifications and features of MM1540CF:

• Automatic switching between energy-saving mode and normal mode
• Current consumption (energy-saving mode): 60µA
• Current consumption (normal mode): 1.5mA
• Uses one photocoupler to control oscillator primary side
• One photocoupler is used to control rated voltage and rated current and switching between energy-saving and normal modes

Application Scenarios

The MM1540CF IC chip is commonly used in AC adaptors with energy-saving functions. It can be applied to various electronic devices that require efficient power usage to reduce environmental impact and lower energy costs.

Comparison

• Reduces power consumption through automated energy-saving mode
• Smaller in size
• Requires fewer external components

• The IC chip may not be suitable for AC adaptors that do not support energy-saving mode or have other control mechanisms.
