MX5241 is a high-end current sensing, 2MHz high brightness LED driver. The input voltage range is from 5.5V to 36V. The output current is set by an external resistor. The DIM pin realizes the brightness control function. MX5241 is especially suitable for applications with a wide input voltage range. The high-end current detection reaches ±5% current accuracy, while requiring only a few external components. Due to the use of hysteresis control, MX5241 has a very fast response speed to load transients and a high suppression ratio to input voltage. The inductor current ripple is 20%. The maximum operating frequency can reach 2MHz. The operating temperature range is from -40 to 125 degrees. It uses SOT23-6 package.

The TPS 434 thermopile detector features an extremely small absorber size and low temperature coefficient of sensitivity, making it suitable for high precision pyrometers and ear thermometers.
