Please refer to the LTC7800 data sheet for a complete description of the part operation and application information. The EXTVCC pin permits the LTC7800 to be powered from the output of the switching regulator or other available source, reducing power dissipation and improving efficiency.
#Ic 7800 power supply oem drivers#
The LTC7800 features two integrated 5V gate drivers with 20ns deadtime which is good for GaN transistors or logic-level MOSFETs to maximize efficiency. A mode selector allows the DC2786A to operate in forced continuous operation, pulse-skipping or Burst Mode ® operation during light loads. This demo board produces a 3.3V output voltage with up to 10A output current, and is configured with a sense resistor for current sensing. This DC2786A operates over an input voltage range from 8V to 40V, while the LTC7800 can operate up to 60V. It features the LTC7800, a low quiescent current high frequency (programmable fixed frequency from 320kHz up to 2.25MHz) synchronous step-down DC/DC controller housed in a small 3mm x 4mm QFN package.

This demo board produces a 12V output voltage with up to 20A output current, and is configured with a sense resistor for current sensing. This DC2736A operates over an input voltage range from 30V to 55V, while the LTC7800 can operate up to 60V. It features the LTC7800, a low quiescent current high frequency (programmable fixed frequency from 320kHz up to 2.25MHz) synchronous step-down DC/DC controller housed in a small 3mm × 4mm QFN package. The PLLIN/MODE pin selects among Burst Mode operation, pulse-skipping mode, or continuous conduction mode at light loads.ĭemonstration circuit 2736A is a single output high voltage nonisolated synchronous step-down converter that drives all GaN transistor power stage. Current foldback limits MOSFET heat dissipation during short-circuit conditions. The TRACK/SS pin ramps the output voltages during start-up. The output voltage of the LTC7800 can be programmed between 0.8V to 24V. A wide 4V to 60V input supply range encompasses a wide range of intermediate bus voltages and battery chemistries. The LTC7800 features a precision 0.8V reference and power good output indicator. OPTI-LOOP ® compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The 50μA no-load quiescent current extends operating run time in battery-powered systems. A constant frequency current mode architecture allows a phase-lockable frequency of up to 2.25MHz. The LTC7800 is a high performance step-down switching regulator DC/DC controller that drives an all N-channel synchronous power MOSFET stage.
