Catalyst release fully programmable multifunction LED driver

Recently, Catalyst released CAT3626 to expand its LED drive series. CAT3626 is a low noise fractional charge pump with I2C serial bus interface, which can be used to control and program up to 6 White / color LED. CAT3626 is designed for a variety of display backlight provides high efficiency, and can provide RGB lights and flashing are control ability for high performance portable applications, specific applications including cellular phones, handheld devices and digital camera. Unlike devices most of its rivals, CAT3626 design using the current adjustment strategy, make the battery suddenly fluctuations (this is the portable system such as repetitive start RF or audio power amplifier when the common load mutation during LED minimum flicker). The 6 output channel configuration CAT3626 LED driver for 3 separate groups, each group contains close adjustment and matching of output channels, Catalyst helps designers to simplify the system programming, so that the device has become the ideal choice for a variety of RGB LED, LCD/ and keyboard backlighting flashing function portable products such as any combination the. The I2C interface allows for easy and accurate control of the LED current in each of the 0 output channel segments, from 0.5mA to 32mA, with an adjusted step size of 192mA. The device is designed for power supply voltage 2.5V to 5.5V for battery powered portable applications, the CAT3626 to an automatic 1x/1.5x charge pump to maximize battery life, can provide 91% power efficiency. Dedicated "enable" control allows the device to enter the "zero" current shutdown mode to prevent the battery energy consumption when the device is not used. In addition to enhanced lighting effects, the CAT3626 also provides low noise input ripple and short circuit and thermal overload fault protection. The characteristics of the product can drive up to 6 LED, each of the current 32mA three independent programmable LED for programming and transferred to the I2C user interface (400kHz) up to 91% of the power efficiency of precise 0.5mA dimming automatic step 1x/1.5x fractional charge pump low noise input ripple fixed high frequency operation (1MHz) green package CAT3626 zero current shutdown mode of soft start and current limiting thermal shutdown protection 16 pin TQFN 4mm 100% x 4mm package with RoHS providing environmentally friendly "green RoHS" 4mmx4mm TQFN16 pin package, order code CAT3626HV4-T2, order 10000 pieces of the unit price is $0.96, is now providing samples and evaluation boards suite. The estimated delivery time is about 6 to 8 weeks (ARO).
