ISL9111
ISL9111 is High Efficiency Synchronous Boost Converter manufactured by Renesas.
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.
