LINEAR TECHNOLOGY
The LT3757IDD#PBF is a current-mode DC/DC Controller which is capable of generating either positive or negative output voltages. It can be configured as either a boost, flyback, SEPIC or inverting converter. It drives a low side external N-channel power MOSFET from an internal regulated 7.2V supply. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages. The operating frequency of the controller can be set with an external resistor over a 100kHz to 1MHz range and can be synchronized to an external clock using the SYNC pin. A low minimum operating supply voltage of 2.9V and a low shutdown quiescent current of less than 1μA, makes the controller ideal. It features soft-start and frequency fold back functions to limit inductor current during start-up and output short-circuit. Positive or negative output voltage programming with a single feedback pin Current mode control provides excellent transient response Synchronizable to an external clock Internal 7.2V Low dropout voltage regulator Programmable input undervoltage lockout with hysteresis Programmable soft-start Supply Voltage Min: 2.9V Supply Voltage Max: 40V No. of Outputs: No. of Outputs: 1 Output Duty Cycle (%): - Controller IC Case Style: DFN No. of Pins: 10Pins Switching Frequency: 1MHz Topology: Boost, Flyback, Inverting, SEPIC 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) Find similar products grouped by common attribute
