TPS61161A 采用 2mm x 2mm 封装的具有 PWM 亮度控制的白光 LED 驱动器。 多达 10 个串联的 LED
TPS61161A 描述
With a 40-V rated integrated switch FET, the TPS61160A/61A is a boost converter that drives up to 10 LEDs in series. 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 TPS61160A/61A does not burst the LED current; therefore, it does not generate audible noises on the output capacitor.
