Description
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 compensated, fully integrated synchronous boost converters optimized for efficiency with minimal external components. At light load, the device enters skip mode and consumes only 20µA of quiescent current, resulting in higher efficiency at light loads and maximum battery life.
The ISL9111 and ISL9111A address both rechargeable and non-rechargeable battery applications. The ISL9111 has a UVLO feature, which will internally shut off at 0.7V protecting a rechargeable battery. The ISL9111A has this feature disabled to maximize the usable life of a non-rechargeable single cell battery. The parts are available in fixed 3.0V, 3.3V and 5.0V output voltage versions or an adjustable output voltage version (ADJ). The fixed output voltage version also provides a FAULT pin for fault condition monitoring. The ISL9111 and ISL9111A are available in a 6 Ld SOT-23 package.
