The TPS92070 is an advanced PWM controller ideal for use in low-power, offline, LED lighting applications. The integrated dimming interface circuitof the TPS92070 features a non-dissipative dimmer trigger control circuit. The TPS92070 controller provides DC LED current with no photometric rippleeffects. The DC current also results in higher efficacy of the LEDs. The TPS92070 provides exponentially controlled light output based on the external dimmer position. High power factor is achieved with a valley fill circuit. Once a leading-edge dimmer is detected, the TPS92070 sets an output to disable the PFC circuit and thus optimizes driver operation. The LED current sense precision error amplifier implements deep dimming. The TPS92070 current sensing scheme provides tight current regulation andeliminates the need for an optocoupler. The tight current regulation allows for strong color and intensity matching amongst individual bulbs or luminaires.The TPS92070 also contains a variety of protection features including cycle-by-cycle peak-current limit, overcurrent protection, open-LED (outputovervoltage) protection, undervoltage lockout, and thermal shutdown.
