TEXAS INSTRUMENTS TPS61161ADRVT. 芯片, 白光二极管驱动器, 升压, SON-6
The is a white LED Driver with PWM brightness control. The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency and allows for the use of small external components. The default white LED current is set with the external sensor resistor Rset and the feedback voltage is regulated to 200mV, as shown in the typical application. During the operation, the LED current can be controlled by a pulse width modulation PWM signal applied to the CTRL pin through which the duty cycle determines the feedback reference voltage. In PWM dimming mode, the TPS61161A does not burst the LED current, therefore, it does not generate audible noises on the output capacitor. For maximum protection, the device features integrated open LED protection that disables the TPS61161A to prevent the output from exceeding the absolute maximum ratings during open LED conditions.
