The CAT4240TD-GT3 from ON Semiconductor is a DC/DC step-up converter specifically designed for driving LEDs with accurate constant current. It operates at a fixed switching frequency of 1 MHz, enabling the use of small external components. This boost LED driver is ideal for mid-size and large panel displays, capable of driving up to ten white LEDs in series with a high-voltage output stage.
Key electrical specifications include a switch current limit of 750 mA, an output voltage capability of up to 38 V, and an efficiency of up to 94%. The device offers low quiescent ground current of 0.6 mA and a shutdown current of less than 1 µA. It supports both analog and PWM dimming methods, providing flexibility in control. The CAT4240TD-GT3 also incorporates safety features such as thermal overload protection, overload current limiting, and open LED overvoltage protection.
Packaged in a space-saving, low-profile 5-lead thin SOT23 (TSOT-23-5) package, this component is suitable for applications where board space is critical. It operates over an ambient temperature range of -40°C to 85°C. The device is Pb-Free, Halogen Free/BFR Free, and RoHS Compliant.
Applications include GPS navigation systems, portable media players, and handheld devices like digital cameras, where efficient and reliable LED driving is required.
