ISL9113A
Low Input Voltage and High Efficiency, Synchronous Boost Converter with 1.3A Switch
FN8620 Rev 1.00 January 4, 2017
The ISL9113A provides a power supply solution for devices powered by three-cell alkaline, NiCd, NiMH, or one-cell Li-Ion/Li-Polymer batteries. It offers either a fixed 5V or an adjustable output option for USB-OTG or portable HDMI applications. The device is guaranteed to supply 500mA from a 3V input and 5V output, and has a typical 1.3A peak current limit. High 1.8MHz switching frequency allows for the use of tiny, low-profile inductors, and ceramic capacitors to minimize the size of the overall solution.
The ISL9113A is an internally compensated, fully integrated synchronous converter optimized for efficiency with minimal external components.
