Linear Technology LT3758IMSE#PBF
- Part Number:
- LT3758IMSE#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3752049-LT3758IMSE#PBF
- Description:
- IC REG CTRLR MULT TOP 10MSOP
- Datasheet:
- LT3758IMSE#PBF
Description
The LT3758/LT3758A are wide input range, current mode, DC/DC controllers capable of generating either positive or negative output voltages. They can be configured as either a boost, flyback, SEPIC, or inverting converter. The LT3758/LT3758A drive 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 LT3758/LT3758A 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 minimum operating supply voltage of 5.5V, and a low shutdown quiescent current of less than 1μA, make the LT3758/LT3758A ideally suited for battery-powered systems.
The LT3758/LT3758A feature soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit. The LT3758A has improved load transient performance compared to the LT3758.
