Equipped with PWM/PFM automatic switching function, synchronous rectification method, maximum output current 2A.
The output current supports up to a maximum of 2A, and to ensure efficient voltage conversion even under light load conditions, it is equipped with a function that automatically switches between PFM (Pulse Frequency Modulation) mode and PWM (Pulse Width Modulation) mode according to the output current. This feature allows the product to achieve both support for heavy loads and high efficiency under light loads. Additionally, it includes a power good function and a variable soft start time function, so when using this product to drive devices that require multiple voltages, external components for power sequence control are unnecessary, making it easy to implement sequence control.
