The TPS61165 is a boost converter with a 40-V rated integrated switch FET, designed to drive LEDs in series. It operates at a 1.2-MHz fixed switching frequency with a 1.2-A switch current limit. The device supports flexible brightness control through either a one-wire digital EasyScale interface or a PWM signal applied to the CTRL pin. It includes integrated 38V open-LED protection, a 200-mV reference voltage with 2% accuracy, and a built-in soft-start feature to prevent inrush current.
