The LTC7860 high efficiency surge stopper protects loads from high voltage transients. High efficiency permits higher currents and smaller solution sizes. During an input overvoltage event, such as a load dump in vehicles, the LTC7860 controls the gate of an external MOSFET to act as a switching DC/DC regulator (PROTECTIVE PWM mode). This operation regulates the output voltage to a safe level, allowing the loads to operate through the input over-voltage event. During normal operation (SWITCH-ON mode), the LTC7860 turns on the external MOSFET continuously, passing the input voltage through to the output. An internal comparator limits the voltage across the current sense resistor and regulates the maximum output current to protect against overcurrent faults.An adjustable timer limits the time that the LTC7860 can spend in overvoltage or overcurrent regulation. When the timer expires, the external MOSFET is turned off until the LTC7860 restarts after a cool down period. By strictly limiting the time in PROTECTIVE PWM Mode when the power loss is high, the components and thermal design can be optimized for normal operation and safely operate through high voltage input surges and/or overcurrent faults. An additional PMOS can be added for reverse battery protection.Applications Industrial and Automotive Power Telecom Power Vehicle Power Including ISO7637 Military Power Including MIL1275

The ADP130 is a low quiescent current, low dropout linear regulator. It is designed to operate in dual-supply mode with an input voltage as low as 1.2 V to increase efficiency and provide up to 350 mA of output current. The low 17 mV dropout voltage at a 100 mA load improves efficiency and allows operation over a wider input voltage range.A dual-supply power solution typically improves conversion efficiency over a single-supply solution because the higher VBIAS supply powers the part, and the lower VIN supply delivers current to the load. The power dissipated in the device is thereby reduced. The ADP130 is optimized for stable operation with small 1 ?F ceramic output capacitors. The ADP130 delivers good transient performance with minimal board area.The ADP130 is available in fixed output voltages ranging from : 0.80 V to 3.0 V.The ADP130 has a typical internal soft start time of 200 ?s. Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. The ADP130 is available in a tiny 5-lead TSOT package for the smallest footprint solution to meet a variety of portable power applications.ApplicationsMobile phonesDigital camera and audio devicesPortable and battery-powered equipmentPost dc-to-dc regulationData Sheet, Rev. 0, 8/08

The LT3758A operates over an input range of 5.5V to 100V, and features a novel FBX pin architecture, which allows it to be connected directly to a resistor divider from either a positive output voltage or a negative output voltage.

The ADA4858-3 (triple) is a single-supply, high speed current feedback amplifier with an integrated charge pump that eliminates the need for negative supplies to output negative voltages or output a 0 V level for video applications. The 600 MHz, ?3 dB bandwidth and 600 V/?s slew rate make this amplifier well suited for many high speed applications. In addition, its 0.1 dB flatness out to 85 MHz at G = 2, along with its differential gain and phase errors of 0.01% and 0.02? into a 150 ? load, make it well suited for professional and consumer video applications.This triple operational amplifier is designed to operate on supply voltages of 3.3 V to 5 V, using only 42 mA of total quiescent current, including the charge pump. To further reduce the power consumption, it is equipped with a power-down feature that lowers the total supply current to as low as 2.5 mA when the amplifier is not being used. Even in power-down mode, the charge pump can be used to power external components. The maximum output current for external use is 50 mA at ?3 V. The amplifier also has a wide input common-mode voltage range that extends from 1.8 V below ground to 1.2 V below the positive rail at a 5 V supply.The ADA4858-3 is available in a 16-lead LFCSP, and it is designed to work over the extended industrial temperature range of ?40?C to +105?C.ApplicationsProfessional videoConsumer videoImagingActive filtersData Sheet, Rev.

The ADF7023 is a very low power, high performance, highly integrated 2FSK/GFSK/OOK/MSK/GMSK transceiver designed for operation in the 862 MHz to 928 MHz and 431 MHz to 464 MHz frequency bands, which cover the worldwide license-free ISM bands at 433 MHz, 868 MHz, and 915 MHz. It is suitable for circuit applications that operate under the European ETSI EN300-220, the North American FCC (Part 15), the Chinese short-range wireless regulatory standards, or other similar regional standards. Data rates from 1 kbps to 300 kbps are supported.The transmit RF synthesizer contains a VCO and a low noise fractional-N PLL with an output channel frequency resolution of 400 Hz. The VCO operates at 2? or 4?, the fundamental frequency to reduce spurious emissions. The receive and transmit synthesizer bandwidths are automatically, and independently, configured to achieve optimum phase noise, modulation quality, and settling time. The transmitter output power is programmable from ?20 dBm to +13.5 dBm, with automatic PA ramping to meet transient spurious specifications. The part possesses both single-ended and differential PAs, which allows for Tx antenna diversity.The receiver is exceptionally linear, achieving an IP3 specification of ?12.2 dBm and ?11.5 dBm at maximum gain and minimum gain, respectively, and an IP2 specification of 18.5 dBm and 27 dBm at maximum gain and minimum gain, respectively. The receiver achieves an interference blocking specification of 66 dB at ?2 MHz offset and 74 dB at ?10 MHz offset. Thus, the part is extremely resilient to the presence of interferers in spectrally noisy environments. The receiver features a novel, high speed, automatic frequency control (AFC) loop, allowing the PLL to find and correct any RF frequency errors in the recovered packet.A patent pending, image rejection calibration scheme is available through a program download. The algorithm does not require the use of an external RF source nor does it require any user intervention once initiated. The results of the calibration can be stored in nonvolatile memory for use on subsequent power-ups of the transceiver.See data sheet for additional information.Applications Smart metering IEEE 802.15.4g Wireless MBUS Home automation Process and building control Wireless sensor networks (WSNs) Wireless healthcare
