The LT1172CT is a constant frequency current mode DC-DC switching controller designed for Boost, Flyback, and SEPIC topologies. It operates from an input voltage range of 3V to 40V and provides an output voltage adjustable from 1.244V up to 40V. The device features a 1.25A maximum switch current and a typical supply current of 6mA, with a shutdown current of only 50µA. The switching frequency is nominally 100kHz and can be synchronized to an external clock in the range of 120kHz to 160kHz. The LT1172CT is a monolithic, non-synchronous, single-output controller. It is suitable for a variety of power conversion applications requiring high input voltage capability and flexible topology support. The operating temperature range is 0°C to 70°C.
