Description
General part information
LT3959 Series
The LT3959 is a wide input range, current mode, DC/DC controller which is 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 VINor 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.The LT3959 features soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit. A window comparator on the FBX pin reports via thePGOODpin, providing output voltage status indication.ApplicationsAutomotiveTelecomIndustrial
