TPS61165 Description
With a 40-V rated integrated switch FET, the TPS61165 device is a boost converter that drives LEDs in series. The boost converter runs at a 1.2-MHz fixed switching frequency with 1.2-A switch current limit, allowing 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 200 mV, as shown in the Typical...
