TPS92070PWR

高效率的调光LED照明控制器 High-Efficiency Integrated Dimming LED Lighting Controller

DESCRIPON

The TPS92070 is an advanced PWM controller ideal for use in low-power, offline, LED lighting applications. The integrated dimming interface circuit of the TPS92070 features a non-dissipative dimmer trigger control circuit. The TPS92070 controller provides DC LED current with no photometric ripple effects. The DC current also results in higher efficacy of the LEDs.
