说明

  • PMP6015, reference design provides a high-brightness LED driver based on the TPS92075. It is designed to operate with an input voltage in the range of 90VAC to 132VAC with a 120 VAC nominal input voltage. This design is set up for an 185mA output current with an output voltage range of 46 V to 54 V. The Max at Max circuit uses simple low cost components to adjust the converter off-time and the output current. A small capacitance transfers a small amount of energy when the TRIAC edge is present, filters it and creates a small current which adds to the existing off-time charge current from VCC. The effect is a shortened off time and increased output current, only when a TRIAC is present
