MAX1790 Overview
High switching frequency (640kHz or 1.2MHz selectable) allows easy filtering and faster loop performance. An external pensation pin provides the user flexibility in determining loop dynamics, allowing the use of small, low equivalent-series-resistance (ESR) ceramic output capacitors. The device can produce an output voltage as high as 12V from an input as low as 2.6V.
