TPS61165 采用 2mm x 2mm QFN 封装的白光 LED 驱动器
TPS61165 描述
With a 40-V rated integrated switch FET, the TPS61165 is a boost converter that drives up to 10 LEDs in series. The boost converter runs at a 1.2-MHz fixed switching frequency with 1.2-A switch current limit, and allows for the use of a high brightness LED in general lighting.
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 using the 1 wire digital interface (Easyscale protocol) through the CTRL pin. Alternatively, a pulse width modulation (PWM) signal can be applied to the CTRL pin through which the duty cycle determines the feedback reference voltage
