ISL78113A

DATASHEET ISL78113A Low Input Voltage and High Efficiency Synchronous Boost Converter with 1.3A Switch FN8638 Rev 0.00 May 1, 2014 The ISL78113A provides a tiny and convenient boost power supply solution to generate a regulated output up to 500mA from any sub-5V secondary rail found in an automotive electrical system, including battery powered applications (NiCd, NiMH, or one-cell Li-Ion/Li-Polymer). It offers an adjustable output (3.0V to 5.2V) supporting USB-OTG or HDMI applications. The device is able to supply 500mA from a 3V input and 5V output, and has a typical 1.3A peak current limit. The ISL78113A is a fully integrated, internally compensated, synchronous converter optimized to maximize efficiency and reduce the overall solution size and bill of materials. Its high 2MHz switching frequency allows the use of tiny, low-profile inductors and chip capacitors. It also eliminates potential interference within the AM radio band and the external EMI filtering needed for converters ...
