Demonstration circuit 2728A is a high voltage, dual output boost converter with 12V to 24V input range. The output voltage is adjustable from VIN to 48V. Each output can supply 5A maximum load current. The demo board has a LTC7880 controller, which is a 60V dual output step-up controller with digital power system management. Please see LTC7880 data sheet for more detailed information. DC2728A powers up to default settings and produces power based on configuration resistors or its nonvolatile memory (NVM) without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter. To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlay® onto your PC and use ADI’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on-the-fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.

The DC2733 is a demonstration system for the LTC4249, 65V Dual Electronic Circuit Breaker with Current Monitors. The LTC4249 provides dual independent 1.2A, 75mΩ circuit breakers that can function independently or work together in parallel. Each circuit breaker channel has its own enable, ready, and IMON pins. The DC2733 demo board gives access to both channels of the LTC4249, including the independent RDY and IMON outputs and the EN inputs. Resistors at the IMON pins set the circuit breaker thresholds as well as the IMON current-to-voltage gains. The IC draws power from the IN1 input.

Demonstration circuit 1640A is a 1.5V/20A synchronous buck converter operating with a switching frequency of 300kHz over an input voltage range of 4.5V to 14V. 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 2mΩ /1% sense resistor for accurate current sensing with a low DCR ferrite inductor. The fixed on-time valley current mode topology of the LTC3833 allows for a fast load step response.

The LTC4359 is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. It controls the forward-voltage drop across the MOSFET to ensure smooth current delivery without oscillation even at light loads. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. A shutdown mode is available to reduce the quiescent current to 9?A for load switch and 14?A for ideal diode applications.When used in high current diode applications, the LTC4359 reduces power consumption, heat dissipation, voltage loss and PC board area. With its wide operating voltage range, the ability to withstand reverse input voltage, and high temperature rating, the LTC4359 satisfies the demanding requirements of both automotive and telecom applications. The LTC4359 also easily ORs power sources in systems with redundant supplies.Applications Automotive Battery Protection Redundant Power Supplies Supply Holdup Telecom Infrastructure Computer Systems/Servers Solar Systems
