LTC1871-7
High Input Voltage,

Flyback and SEPIC Controller
DescripTion
The LTC
®
1871-7 is a current mode, boost, flyback and
SEPIC controller optimized for driving 6V-rated MOSFETs
in high voltage applications. The LTC1871-7 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 LTC1871-7 well suited for battery-operated
systems. For applications requiring constant frequency
operation, Burst Mode operation can be defeated using
the MODE/SYNC pin. The LTC1871-7 is available in the
10-lead MSOP package.
