DATASHEET ISL9111, ISL9111A Low Input Voltage, High Efficiency Synchronous Boost Converter with 1A Switch FN7602 Rev.4.00 Jun 4, 2012 The ISL9111 and ISL9111A provide a power supply solution for single-cell, dual-cell, or three-cell alkaline, NiCd or NiMH battery-powered applications. The device has a typical 0.8V start-up voltage and is capable of supplying up to 5.25V output voltage. Both devices are guaranteed to supply 100mA from a single-cell input and 240mA from a dual-cell input when output is 3.3V. High 1.2MHz switching frequency allows for the use of tiny, low-profile inductors and ceramic capacitors to minimize the size of the solution.
