The LTC7812 is a high performance synchronous Boost+Buck DC/DC switching regulator controller that drives all N-channel power MOSFET stages. It contains independent step-up (boost) and step-down (buck) controllers that can regulate two separate outputs or be cascaded to regulate an output voltage from an input voltage that can be above, below or equal to the output voltage. The LTC7812 operates from a wide 4.5V to 38V input supply range. When biased from the output of the boost regulator, the LTC7812 can operate from an input supply as low as 2.5V after start-up. The 33?A no-load quiescent current extends operating run time in battery-powered systems.Unlike conventional buck-boost regulators, the LTC7812?s cascaded Boost+Buck solution has continuous, nonpulsating, input and output currents, substantially reducing voltage ripple and EMI. The LTC7812 has independent feedback and compensation points for the boost and buck regulation loops, enabling a fast output transient response that can be easily optimized externally.Applications Automotive and Industrial Power Systems High Power Battery Operated Systems

Demonstration circuit 2423A showcases the LTM9100 Isolated Switch Controller in either a typical 48V application (–A) or in a high voltage 380V application (–B). The board may be configured for either high side or low side operation, dependent on the connection of external supply and load to the banana jacks. An on board capacitive load may also be wired into the circuit. LEDs indicate the presence of input and output voltage.

The ADP8860SHIELD-EVALZ and the ADP8861SHIELD-EVALZ incorporate light emitting diodes (LEDs) for quick and easy evaluation of the ADP8860 and the ADP8861. Note that only the ADP8860SHIELD-EVALZ has dual light intensity sensors. The ADP8860SHIELD-EVALZ and the ADP8861SHIELD-EVALZ follow the form factor of a regular Arduino® shield to allow compatibility with microcontroller boards that use the same interface. These evaluation boards also incorporate a separate header dedicated to I2C communications. The ADP8860 and the ADP8861 are 7-channel LED drivers that utilizes a charge pump with selective gain for maximum efficiency. The LEDs driven by either device are programmable for maximum current and fade in and out times via the I2C interface. Only the ADP8860 has a programable light intensity threshold that can be set via the I2C interface of the device. Each channel can handle up to 30 mA (typical), except for the seventh channel, which can handle 60 mA (typical). Each channel can be unified to have the same fade in time and fade out time, or each channel can have an individual fade in time and fade out time for greater flexibility. For full details on the ADP8860 and the ADP8861, see the ADP8860 and the ADP8861 data sheets, which should be consulted in conjunction with the user guide when using these evaluation boards.
