Demonstration circuits 2297A-A and 2297A-B feature the LT8570 and LT8570-1 in a boost configuration. These demo circuits demonstrate small size and low component count. Both converters are designed to convert a 5V to 10V source to 12V. The DC2297A-A (LT8570) provides 125mA of output current, and the DC2297A-B (LT8570-1) provides 60mA of output current.

The LTC3890-1 is a high performance dual step-down switching regulator DC/DC controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows a phase-lockable frequency of up to 850kHz. Power loss and supply noise are minimized by operating the two controller output stages out-of-phase.The 50?A no-load quiescent current extends operating life in battery-powered systems. OPTI-LOOP? compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. A wide 4V to 60V input supply range encompasses a wide range of intermediate bus voltages and battery chemistries.Independent TRACK/SS pins for each controller ramp the output voltages during start-up. Current foldback limits MOSFET heat dissipation during short-circuit conditions. The PLLIN/MODE pin selects among Burst Mode operation, pulse-skipping mode, or continuous conduction mode at light loads.For a leadless 32-pin QFN package with additional features of adjustable current limit, clock out, phase modulation and two PGOOD outputs, see the LTC3890 data sheet.

The LTC2000 is a family of 16-/14-/11-bit 2.5Gsps current steering DACs with exceptional spectral purity.The single (1.25Gsps mode) or dual (2.5Gsps mode) port source synchronous LVDS interface supports data rates of up to 1.25Gbps using a 625MHz DDR data clock, which can be either in quadrature or in phase with the data. An internal synchronizer automatically aligns the data with the DAC sample clock.Additional features such as pattern generation, LVDS loopout and junction temperature sensing simplify system development and testing.A serial peripheral interface (SPI) port allows configuration and read back of internal registers. Operating from 1.8V and 3.3V supplies, the LTC2000 consumes 2.2W at 2.5Gsps and 1.3W at 1.25Gsps.Applications Broadband Communication Systems DOCSIS CMTS Direct RF Synthesis Radar Instrumentation Automatic Test Equipment
