Description

EE25 is Transformer for Single stage LED driver.

A single-stage LED driver is a type of LED driver circuit that integrates both power factor correction (PFC) and LED driving functions into a single stage, as opposed to the traditional two-stage approach where PFC and LED driving are separate stages. In this context, a transformer is not typically used in a single-stage LED driver circuit.

The primary purpose of a transformer in a power supply circuit is to step-up or step-down the voltage, and it is commonly used in traditional non-isolated (flyback or forward) LED drivers. However, in a single-stage LED driver, the topology is usually based on a boost converter with power factor correction (PFC), and the transformer is eliminated to reduce size, cost, and complexity.
