Renesas Electronics ISL9111AEHADJZ-T7A, Boost Converter, Boost Converter 240mA

The Renesas Synchronous Boost Converter with 1A Switch is 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.

Low quiescent current of 20μA (typical)
100mA output current VIN 0.9V
240mA output from VIN 1.8V
Logic control shutdown (Iq < 1μA)
Output voltage up to 5.25V
Output disconnect during shutdown
