LT3759EMSE Product Details
The LT3759EMSE 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.
The LT3759EMSE drives a low side external N-channel power MOSFET. An internal LDO regulator draws power from VIN or DRIVE to provide up to a 4.75V supply for the gate driver. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages. The operating frequency of LT3759EMSE 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 LT3759EMSE 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 the PGOOD pin, providing output voltage status indication. The device is available in a 12-Lead exposed pad MSOP package.
