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.
The ISL9111 and ISL9111A are internally co...
