General Description

The ZCC3715 is a highly integrated boost converter designed for applications requiring high voltage and high efficiency solution. The ZCC3715 integrates a 20V power switch, it can output up to 18V from input of a Li+ batteryor two cell alkaline batteries in series.

The ZCC3715 operates with a switching frequency at 1.2MHz. This allows the use of small external components. ZCC3715 has typical 4A switch current limit. It has 1.5mS built-in soft start time to minimize the inrush current. The ZCC3715 also implements output short circuit protection,output over-voltage protection and thermal shutdown.The ZCC3715is available in a small SOT23-6 package.
