TTP932
1A LED Driver with internal switch
Outline
TTP932 is a high efficiency , constant current , continuous mode inductive step-down converter, designed for driving constant current to high power（single or multiple）LED with only 4 external components. TTP932 operates from input supply between 5V and 33V and provides an externally adjustable output current of up to 1A.
The TTP932 is specifically designed with PFM control to enhance the efficiency up to 95% . The Output current can be modify by an external resister , and can adjusted , by applying an external control signal to the DIM pin , The DIM pin will accept a PWM waveform.
