LTC7812 Datasheet 38v Synchronous Boost+buck Controller

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC7812 Low IQ, 38V Synchronous Boost+Buck Controller.

General Description

The LTC®7812 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.

Key Features

  • n Synchronous Boost and Buck Controllers n When Cascaded, Allows VIN Above, Below or Equal to Regulated VOUT n Output Remains in Regulation Through Input Dips (e. g. , Cold Crank) Down to 2.5V n Wide Bias Input Voltage Range: 4.5V to 38V n Low Input and Output Ripple n Low EMI n Fast Output Transient Response n High Light Load Efficiency n Low Operating IQ: 33µA (Both Channels On) n Low Operating IQ: 28µA (Buck Channel On) n RSENSE or Lossless DCR Current Sensing n Buck Output Voltage.
