LINEAR TECHNOLOGY
The LT3800IFE#PBF is a 200kHz fixed frequency high voltage synchronous current-mode step-down Switching Regulator Controller drives standard gate N-channel power MOSFETs and can operate with input voltages from 4 to 60V. An on board regulator provides IC power directly from VIN and provides for output-derived power to minimize VIN quiescent current. MOSFET drivers employ an internal dynamic bootstrap feature, maximizing gate-source "ON" voltages during normal operation for improved operating efficiencies. It incorporates burst mode operation, which reduces no load quiescent current to under 100µA. Light load efficiencies are also improved through a reverse inductor current inhibit, allowing the controller to support discontinuous operation. Both the burst mode operation and the reverse-current inhibit features can be disabled if desired. Adaptive non-overlap circuitry prevents switch shoot-through Reverse inductor current inhibit for discontinuous operation improves efficiency with light loads Output slew rate controlled soft-start with auto-reset Standard gate N-channel power MOSFETs Current limit unaffected by duty cycle Reverse overcurrent protection 100μA No load quiescent current Low 10μA Current shutdown 1% Regulation accuracy Supply Voltage Min: 4V Supply Voltage Max: 20V No. of Outputs: No. of Outputs: 1 Output Duty Cycle (%): - Controller IC Case Style: TSSOP No. of Pins: 16Pins Switching Frequency: 220kHz Topology: Synchronous Buck (Step Down) Operating Temperature Min: -40°C Operating Temperature Max: 125°C Packaging: Cut Tape Product Range: - Automotive Qualifications Standard: - MSL: MSL 1 - Unlimited Output Current: 15 A SVHC: No SVHC (17-Dec-2015) Output Voltage: 36 V Find similar products grouped by common attribute
