The LTC2952 is a power management device that features three main functions: pushbutton on/off control of system power, ideal diode PowerPath? controllers and system monitoring. The LTC2952?s pushbutton input, which provides on/off control of system power, has independently adjustable ON and OFF debounce times. A simple microprocessor interface involving an interrupt signal allows for proper system housekeeping prior to power-down. The ideal diode PowerPath controllers provide automatic low loss switchover between two DC sources by regulating two external P-channel MOSFETs to have a small 20mV forward drop. High reliability systems may utilize the LTC2952?s monitoring features to ensure system integrity. These features include: power-fail, voltage monitoring and ?P watchdog. The LTC2952 operates over a wide operating voltage range to accommodate a large variety of input power supplies. The part?s combination of low 20mV external MOSFET regulation and very low standby current matches battery powered and power conscious application requirements.Applications Desktop and Notebook Computers Portable Instrumentations Cell Phones, PDA and Handheld Computers Servers and Computer Peripherals Battery Backup Systems

The LTC1503-1.8/LTC1503-2 are switched capacitor step-down DC/DC converters that produce a regulated output from a 2.4V to 6V input. The parts use switched capacitor fractional conversion to achieve high efficiency over the entire input range. No inductors are required. Internal circuitry controls the step-down conversion ratio to optimize efficiency as the input voltage and load conditions vary. Typical efficiency is 25% higher than that of a low dropout (LDO) linear regulator.Regulation is achieved by sensing the output voltage and enabling the internal switching network as needed to maintain a fixed output voltage. This method of regulation enables the parts to achieve high efficiency at extremely light loads. Low operating current (25?A with no load, 5?A in shutdown) and low external parts count (two 1?F flying capacitors and two 10?F bypass capacitors) make the LTC1503-1.8/LTC1503-2 ideally suited for space constrained battery-powered applications. The parts are fully short-circuit and over temperature protected.The LTC1503-1.8/LTC1503-2 are available in 8-pin MSOP and SO packages.Applications Cellular Phones Handheld Computers Smart Card Readers Low Power DSP Supplies Portable Electronic Equipment Handheld Medical Instruments

The ADF4371 allows implementation of fractional-N or Integer N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave voltage controlled oscillator (VCO) design allows frequencies from 62.5 MHz to 32 GHz to be generated.The ADF4371 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allows the user to generate radio frequency (RF) output frequencies as low as 62.5 MHz at RF8x. A frequency multiplier at RF16x generates from 8 GHz to 16 GHz. A frequency quadrupler generates frequencies from 16 GHz to 32 GHz at RF32x. RFAUX8x duplicates the frequency range of RF8x or permits direct access to the VCO output. To suppress the unwanted products of frequency multiplication, a harmonic filter exists between the multipliers and the output stages of RF16x and RF32x.Control of all on-chip registers is through a 3-wire interface. The ADF4371 operates with analog and digital power suppliesranging from 3.15 V to 3.45 V, and 5 V for the VCO power supply. The ADF4371 also contains hardware and software power-down modes.
