LTC1871IMS-7 Integrated Circuit Chip High Input Voltage Current Mode Boost Flyback And SEPIC Controller
Product Description Of LTC1871IMS-7
LTC1871IMS-7 is a current mode, boost, flyback and SEPIC controller optimized for driving 6V-rated MOSFETs in high voltage applications. The LTC1871IMS-7 works equally well in low or high power applications and requires few components to provide a complete power supply solution. The switching frequency can be set with an external resistor over a 50kHz to 1MHz 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 6V and a low shutdown quiescent current of 10µA make the LTC1871IMS-7 well suited for battery-operated systems. For applications requiring constant frequency operation, Burst Mode operation can be defeated using the MODE/SYNC pin. The LTC1871IMS-7 is available in the 10-lead MSOP package.
