LTC7899 Switching Regulator Controller

Analog Devices LTC7899 Switching Regulator Controller is a high-performance DC-DC, negative-to-positive controller that drives all N-channel synchronous MOSFET stages and can operate from input voltages up to 135V. The integrated feedback level shifter allows for easy programming of the positive output voltage with only two resistors. The LTC7899 can also be configured as a step-up (Boost) operation with pass-through. The gate drive voltage for the LTC7899 can be programmed from 5V to 10V to allow the use of logic or standard-level MOSFETs to maximize efficiency.
