OZ9936 operates at a constant operating frequency that eliminates any undesired interference between the controller and LCD panel. OZ9936 drives all types of CCFLs and is able to ignite positive impedance CCFLs.
OZ9936 provides a shutdown delay feature for input brownout condition. The control logic provides a regulated ignition voltage and appropriate protection for over voltage or over-current conditions.
functional description NS4205 is a no filter, D class two-channel audio amplifier. NS4205 uses advanced technology, great in the full bandwidth range To reduce EMI interference, to minimize the impact on other components. NS4205 eliminates the need for filter PWM modulation structure and feedback Resistive built-in way reduces external components, PCB area and system cost. NS4205 built-in overcurrent protection, overheat protection and undervoltage protection, Effectively protect the Chip in the abnormal working conditions are not damaged. And the use of spread spectrum technology to fully optimize the new circuit design, up to 90% of the effect Rate is more suitable for portable audio products. The NS4205 is available in an SOP16 package and is specified over the -40 ° C to 85 ° C operating temperature range.

GENERAL DESCRIPTION The OZ9939 is a high performance, cost-effective CCFL (Cold Cathode Fluorescent Lamp) controller designed for driving large-size Liquid Crystal Display (LCD) applications requiring 2 to 6 CCFLs.
FEATURES • Negative PWM dimming polarity • Constant operating frequency • Drives positive/negative-impedance lamps during ignition • High drive current for external MOSFETs • User-defined ignition time and shutdown delay time • Multiple mode dimming control • Built-in intelligence for ignition and normal operation of CCFLs • Built-in open-lamp protection and over voltage protection for backlight system • Optimized soft-start function
CXA1100, CXA1101, CXA1102 and CXA1163 are ICs including two separate Dolby B type noise reduction processors. Seven devices with four Dolby levels and two types of package are provided for various applications. These devices feature very few external components, which is achieved by integrated filter circuits using integrated thin film capacitors with high capacitance.
O2Micros OZ998 Multi-DIMM Selector supports the switching between a primary SMBus and 3 other secondary SMBus. This function is particularly useful for DIMM devices and the support of Intel’s PAS (Preboot Authentication Service).
