SM8132A規(guī)格書詳情
OVERVIEW
The SM8132A is a charge pump DC/DC converter that switches between ×1and ×1.5 automatically. The SM8132A switches between ×1 and ×1.5 according to detected LED drive current, so that the battery life can be prolonged to the fullest extent. Since the connected LED are all detected for the switching, the SM8132A can respond to the variation of LED forward voltage. 4-channel of LED drive current control circuit is built-in, the SM8132A can control 1 to 4 lights of white LED, which are connected in parallel. The LED drive current per channel is set up by external resistor. Besides, the input signal controlling of EN pin allows ON/OFF and dimming.
