LINEAR TECHNOLOGY
The LT3959EUHE#PBF is a current-mode DC/DC Controller capable of regulating either positive or negative output voltages from a single feedback pin. It can be configured as a boost, SEPIC or inverting converter. It features an internal low side N-channel MOSFET rated for 6A at 40V and driven from an internal regulated supply provided from VIN or DRIVE. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages. The operating frequency of LT3959 can be set over a 100kHz to 1MHz range with an external resistor, or can be synchronized to an external clock using the SYNC pin. It features soft-start and frequency fold back functions to limit inductor current during start-up and output short-circuit. A window comparator on the FBX pin reports via the PGOOD pin, providing output voltage status indication. Positive or negative output voltage programming with a single feedback pin PGOOD output voltage status report Internal 6A/40V power switch Programmable soft-start Synchronizable to an external clock INTVCC Regulator supplied from VIN or DRIVE Programmable input under voltage lockout with hysteresis Supply Voltage Min: 1.6V Supply Voltage Max: 40V No. of Outputs: No. of Outputs: 1 Output Duty Cycle (%): - Controller IC Case Style: QFN No. of Pins: 36Pins Switching Frequency: 1MHz Topology: Boost, Inverting, SEPIC Operating Temperature Min: -40°C Operating Temperature Max: 125°C Packaging: Cut Tape Product Range: - Automotive Qualifications Standard: - MSL: MSL 1 - Unlimited Output Current: 6 A SVHC: No SVHC (17-Dec-2015) Find similar products grouped by common attribute
