Milpitas, Calif.—California Micro Devices' family of PhotonIC white LED drivers, which includes the CM9410 and CM9412 devices, features 1-amp drive capability and multiple operating modes that can be programmed via a single-wire interface. The CM9410 comes in a 0.4-mm pitch, chip scale package, touting one-fifth the form factor of equivalent solutions.
The CM9410 and CM9412, working from a 3- to 5.5-volt input, feature torch, two flash modes, and a shutdown mode. Preview and flash currents can be programmed independently via external resistors. The CM9412 (3-by-3 mm DFN) also includes timeout protection for the flash modes. Both products offer a drive capability of up to 1 amp to support flash with high resolution camera sensors. The typical switching frequency is 1 MHz and typical shutdown current is less than 0.3 microamp. These products also feature over-current and over-voltage protection as well as under-voltage lockout and soft-start circuitry to limit inrush current.
