参考设计(4)
230Vac Triac Dimmable 10W LED Driver
PMP6009: This TPS92075 reference design presents the TPS92075 AC-DC controller driving an 80V string of LEDs at 100mA in a buck configuration. It is compatible with most 230Vac triac dimmers.
120Vac Single Stage Non-Dimmable 50W LED Driver Reference Design
PMP6017: This reference design provides a high power ( 50W ) non-isolated, non-dimming LED driver based on the TPS92074. With a nominal input of 120VAC and input range covering 108VAC to 132VAC, the design provides 1 Amp of output current to a 47V nominal stack of LEDs (~16 LEDs). The Buck PFC provides high power factor and low THD.
120Vac Non Dimmable 8W LED Driver
PMP6014: This TPS92074 reference design presents the TPS92074 controller driving a 30V string of LEDs at 250mA in a buck configuration. It is a non dimmable design.
120Vac TRIAC Dimmable LED Driver Reference Design
PMP6015: This 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 to 54V. 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.
