LTC1871XMS#PBF is a wide input range, current mode, boost, flyback or SEPIC controller that drives an N-channel power MOSFET. LTC1871X is rated to 175°C junction temperature and is 100% tested at 175°C. Intended for low to medium power applications, it eliminates the need for a current sense resistor by utilizing the power MOSFET’s on-resistance, thereby maximizing efficiency.
The IC’s operating frequency can be set with an external resistor over a 65kHz to 900kHz range, and can be synchronized to an external clock using the MODE/SYNC pin. Burst Mode operation at light loads, a low minimum operating supply voltage of 2.5V and a low shutdown quiescent current of 10μA make the LTC1871X ideally suited for battery-operated systems.
For applications requiring constant frequency operation, Burst Mode operation can be defeated using the MODE/SYNC pin. Higher output voltage boost, SEPIC and flyback applications are possible with the LTC1871X by connecting the SENSE pin to a resistor in the source of the power MOSFET.
The LTC1871XMS#PBF is available in the 10-lead MSOP package.
