The ADD5207 is a white LED driver for backlight applications based on high efficiency, current mode, step-up converter technology. It is designed with a 0.15 Ω, 1.5 A internal switch and a pin-adjustable operating frequency between 600 kHz and 1 MHz.The ADD5207 contains four regulated current sources for uniform LED brightness. Each current source can drive up to 25 mA and the LED-driving current is pin adjustable by an external resistor. The ADD5207 drives up to four parallel strings of multiple series-connected LEDs with a ±1.5% current matching between strings.The ADD5207 provides phase shift PWM brightness control methods. LED dimming control is achieved through the PWM input. The device includes an 8 kHz LED-dimming oscillator for driving each current source. The ADD5207 operates over an input voltage range of 6 V to 21 V, but the device can function with a voltage as low as 5.6 V.The ADD5207 also has multiple safety protection features to prevent damage during fault conditions. If any LED is open, the device automatically disables the faulty current source. The internal soft start circuit prevents a high inrush current during startup. Thermal shutdown protection prevents thermal damage.The ADD5207 is available in a low profile, thermally enhanced, 4 mm × 3 mm × 0.75 mm, 14-lead, RoHS-compliant lead frame chip scale package (LFCSP) and is specified over the industrial temperature range of −25°C to +85°C.APPLICATIONS Notebook PCs UMPCs, and monitor displays

The ADM2682E/ADM2687E are fully integrated 5 kV rms signal and power isolated data transceivers with ±15 kV ESD protection and are suitable for high speed communication on multipoint transmission lines. The ADM2682E / ADM2687Einclude an integrated 5 kV rms isolated dc-to-dc power supply that eliminates the need for an external dc-to-dc isolation block.They are designed for balanced transmission lines and comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E).The devices integrate Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver, a differential input receiver, and Analog Devices isoPower® dc-to-dc converter into a single package. The devices are powered by a single 5 V or 3.3 V supply, realizing a fully integrated signal and power isolated RS-485 solution.The ADM2682E/ADM2687E drivers have an active high enable.An active low receiver enable is also provided, which causes thereceiver output to enter a high impedance state when disabled.The devices have current limiting and thermal shutdown features to protect against output short circuits and situations where bus contention may cause excessive power dissipation. The parts are fully specified over the industrial temperature range and are available in a highly integrated, 16-lead, wide-body SOIC package with >8 mm creepage and clearance.The ADM2682E/ADM2687E contain isoPower technology that uses high frequency switching elements to transfer power throughthe transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. Refer to AN-0971 Application Note, Recommendations for Control of Radiated Emissions with isoPower Devices, for details on board layout considerations.Applications Isolated RS-485/RS-422 interfaces Industrial field networks Multipoint data transmission systems

The ADM4168E is a dual RS-422 transceiver suitable for high speed communication on point to point and multidrop transmission lines. The ADM4168E is designed for balanced transmission lines and complies with TIA/EIA-422-B. The differential driver outputs and receiver inputs feature electrostatic discharge (ESD) circuitry that provides protection up to ±15 kV human body model (HBM) and ±8 kV IEC 61000-4-2 (contact and air discharge). The ADM4168E operates from a single 5 V power supply. Excessive power dissipation caused by bus contention or output shorting is prevented by short-circuit protection circuitry. Short-circuit protection circuits limit the maximum output current to −150 mA during fault conditions. The receivers of the ADM4168E contain a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating). The ADM4168E is fully specified over the commercial and industrial temperature ranges and is available in a 16-lead TSSOP package.Applications RS-422 interfaces High data rate motor control Single-ended to differential signal conversion Point to point and multidrop transmission systems
