LINEAR TECHNOLOGY
The LT3742EUF#PBF is a dual step-down DC/DC Switching Regulator Controller that drives high side N-channel power MOSFETs. A 500kHz fixed frequency current-mode architecture provides fast transient response with simple loop compensation components and cycle-by-cycle current limiting. The output stages of the two controllers operate 180° out of phase to reduce the input ripple current, minimizing the noise induced on the input supply and allowing less input capacitance. An internal boost regulator generates a bias rail of VIN 7V to provide gate drive for the N-channel MOSFETs allowing low dropout and 100% duty cycle operation. The LT3742 can be used for applications where both controllers need to operate independently, or where both controllers are used to provide a single higher current output. Out-of-phase controllers reduce required input capacitance and power supply induced noise Internal boost converter provides bias rail for N-channel MOSFET gate drive Power good voltage monitor for each output Programmable soft-start Supply Voltage Min: 4V Supply Voltage Max: 30V No. of Outputs: No. of Outputs: 2 Output Duty Cycle (%): 100% Controller IC Case Style: QFN No. of Pins: 24Pins Switching Frequency: 560kHz Topology: 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 SVHC: No SVHC (17-Dec-2015) Output Voltage: 30 V Find similar products grouped by common attribute
