The ADP2114 is a highly versatile, synchronous step-down, switching regulator that can be configured to satisfy a wide range of customer point of load requirements. The two PWM channels can be configured to deliver independent outputs at 2 A and 2 A (or 3 A/1 A) or can be configured as a single interleaved output capable of delivering 4 A. The two PWM channels are 180? phase shifted to reduce input ripple current and reduce input capacitance.The ADP2114 provides high efficiency performance at full loads, enabling high switching frequencies at up to 1.2 MHz. At light loads, the ADP2114 can be set to operate in pulse skip mode for higher efficiency or in forced PWM mode to reduce EMI.The device is designed with an optimized gate slew rate to reduce ENI emissions, allowing the device to supply sensitive, high performance signal chain applications. The frequency can be set to 300 kHz, 600 kHz and 1.2 MHz and can be synchronized to an external clock signal, minimizing the system noise between converters. The bidirectional synchronization pin is also configurable as a 90? out-of-phase output clock, providing the possibility for a stackable multiphase power solution.The ADP2114 input voltage range is from 2.75 V to 5.5 V, and it converts to fixed outputs of 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V that can be set independently for each channel using external resistors. Using a resistor divider, it is also possible to set the output voltage as low as 0.6 V. The ADP2114 operates over the ?40?C to +125?C junction temperature range.ApplicationsPoint-of-load regulationTelecom and networking systemsConsumer electronicsIndustrial and InstrumentationMedical

The HMC908A is a compact, gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), inphase/quadrature (I/Q) downconverter in a leadless, RoHS compliant ceramic leadless chip carrier. This device provides a small signal conversion gain of 11 dB with a noise figure of 2 dB and 25 dB of image rejection at 100 MHz. The HMC908A utilizes a low noise amplifier (LNA) followed by an image rejection mixer that is driven by a local oscillator (LO) buffer amplifier. The image rejection mixer eliminates the need for a filter following the LNA, and removes thermal noise at the image frequency. I and Q mixer outputs are provided and an external 90? hybrid is needed to select the required sideband. The HMC908A is a much smaller alternative to hybrid style image rejection mixer downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface-mount manufacturing techniques.Applications Point to point radios Point to multipoint radios and very small aperture terminals (VSATs) Test equipment and sensors Military end use

Demonstration circuit 1643A is an isolated flyback converter featuring LT3575, a monolithic switching regulator specifically designed for the isolated flyback converter with an integrated 2.5A, 60V NPN transistor. The DC1643A is designed for 5V output from a 10V to 28V DC input. The output current capability depends on the input voltage, proper cooling, and the switch voltage stress. The output current is up to 1.4A when the input is higher than 10V, and 2A when the input is higher than 20V but less than 28V. The output current should not be higher than 2.4A for safe operation.

Demonstration circuit 1626A is a dual output 1.5V/15A and 1.2V/15A synchronous buck converter operating with a switching frequency of 300kHz over an input voltage range of 4.5V to 26V. The demo board comes in two versions. The -A version uses inductor DCR current sensing with an iron powder inductor for high efficiency. The -B version uses a 2.5mΩ sense resistor for accurate current sensing with a low DCR ferrite inductor.
