Abstract:
A driver for a lighting module has driver inputs for receiving a supply voltage from an electronic control gear (ECG) and driver outputs for supplying power to the light-emitting element. The driver also has a ring choke converter (RCC) control circuit with a power switching transistor and with a transformer for supplying power to the driver outputs. The power switching transistor is adapted to control power supplied to the transformer. Coupled to the RCC control circuit, the driver furthermore has a feedback circuit. The feedback circuit is adapted to stabilize the power provided to the light-emitting element.
