A variety of circuit protection devices can be used to help protect LCD screens from damage caused by excessive current or voltage transients. Overcurrent protection may take the form of a fuse or a ...
Dallas Semiconductor, a wholly owned subsidiary of Maxim Integrated Products, introduces the DS3992/DS3994, 2-/4-channel controllers for cold-cathode fluorescent lamps (CCFLs) that are used to ...
Passive circuits for power factor correction (PFC) are simple, reliable, robust, and they don't generate EMI [1-4]. Plus, they offer a low-cost alternative for complying with harmonic current limit ...
LCD circuits often require a –10V voltage at 2 to 15 mA to bias a graphics-LCD-driver IC. You can usually accomplish this task with an external charge-pump IC, such as Maxim’s ICL7660, but that ...
