ONSEMI CAT32TDIGT3 White LED Driver
The CAT32 is a high-efficiency, constant-frequency white LED driver designed for battery-powered applications. It features a step-up DC/DC converter operating at 1.2 MHz, capable of driving up to four white LEDs in series with a regulated current of up to 40 mA. An external resistor sets the LED current, while PWM and logic-based dimming enable precise brightness control. Its low quiescent current, overcurrent and open-circuit protection, and small 6-pin TSOT-23 package make it suitable for portable devices like smartphones, digital cameras, and handheld electronics, ensuring reliable and efficient performance.
