DC459A Demo Board for: LT1946 1.2MHz Boost DC/DC Converter with 1.5A Switch and Soft-Start LT1946A 2.7MHz Boost DC/DC Converter with 1.5A Switch and Soft-Start

Demonstration circuit 2506A is a high voltage, currentmode DC/DC step-down converter featuring the LTC3894. The board operates from an input range of 6V to 150V, and provides a 5V, 3A output. The PMOSFET architecture allows it to operate seamlessly up to 100% duty cycle, and function as a saturated switch below the regulation threshold. This application has undervoltage lockout programmed for a 6V minimum input to assure adequate gate drive for the MOSFET. It operates at 150kHz and may be synchronized to an external clock. A soft-start feature controls output voltage slew rate at start-up, reducing current surge and voltage overshoot. Burst Mode operation that improves efficiency at light loads can be enabled with a jumper. A power good output signal is provided. This board is suitable for a wide range of automotive, telecom, industrial, and other applications. The LTC3894 is available in a thermally enhanced 20-pin TSSOP package with skipped leads to accommodate high voltage creepage and clearance requirements. For other output requirements, see the LTC3894 data sheet or contact the LTC factory.

The LTC2498 is a 16-channel (8-differential) 24-bit No Latency ??? ADC with Easy Drive technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances, and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. The LTC2498 includes a high accuracy temperature sensor and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 16 analog input channels operating in single ended or differential modes) or its internal temperature sensor. The integrated temperature sensor offers 1/30th ?C resolution and 2?C absolute accuracy. The LTC2498 allows a wide common mode input range (0V to VCC), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion after a new channel is selected is valid. Access to the multiplexer output enables optional external amplifiers to be shared between all analog inputs and auto calibration continuously removes their associated offset and drift.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control
