TPS61042 概述The TPS61042 is a high frequency boost converter with constant current output that drives white LEDs or similar. To allow higher flexibility, the TPS61042 can be configured where the brightness can be controlled by an analog signal as well. To avoid possible leakage currents through the LEDs during shutdown, the control pin (CTRL) disables the TPS61042 and disconnects the LEDs from ground. |
