LEA100F-5

LEA100F-5 devices are an AC/DC converter family that produces up to 5 watts of output power from the AC power line. The product line consists of an AC/DC control module, an auxiliary input module, and a DC/DC converter module. The AC/DC converter module provides essential protection and control functions for the auxiliary module, and works with the integrated control system to reduce or eliminate power line disturbances. The AC/DC control module easily integrates with external components, simplifying integration and reducing system costs.

The LEA100F-5 AC/DC converter family is designed for stability, extremely low no/load power consumption, and operation in extreme electrical environments. The integrated magnetic components in the LEA100F-5 products offer superior performance over classic MTBF setups. The line protection feature cuts off the output supply in the event of a surge, avoiding the need for additional line protection components. The LEA100F-5 product line has low start-up and transient surge current requirements due to the advanced power immunity and power management that integrated into the devices.

These features make it suitable for applications that require high efficiency and noise immunity like industrial, consumer and other power supplies, battery charging systems, LED lighting, and renewable energy sources. The LEA100F-5 product family features leading edge technology with advanced power management, allowing for maximum power efficiency in extremely low power requirements.

The LEA100F-5 AC/DC converter consists of two separate components, the main module and the auxiliary board. The main AC/DC control module houses the integrated power supply circuitry, line protection, surge immunity, transient suppression, and advanced power management. The auxiliary module provides compensation, voltage regulation, temperature sensing, and current sensing for the AC/DC converter. The DC/DC converter module is integrated into the AC/DC converter for higher levels of efficiency, improved thermal performance, and reduced component size.

The LEA100F-5 AC/DC converter offers a wide range of performance including maximum efficiency at 82% and over voltage tolerant up to 440VAC. The device is highly robust and can withstand up to 5KV ESD, twice the fault current and high fault tolerance design for abnormal voltage and current conditions. The LEA100F-5 is designed to operate in temperature ranging from -40°C to +85°C, making it ideal for use in extreme environments.

In summary, the LEA100F-5 AC/DC convertor is designed to offer high performance, high reliability, and power efficiency in an extremely low power footprint with advanced power management. The product is suitable for many applications in industrial, consumer, and renewable energy markets and offers excellent protection from no/load power consumption, abnormal voltages, and other power supply challenges.
