FIXED (5.
Features
* Up to 97% Efficiency at Typical Operating Conditions
* Minimum Start-up Voltage
- 0.8V (ISL9111) - 0.6V (ISL9111A)
* Minimum Operating Voltage - 0.7V (ISL9111) - 0.5V (ISL9111A)
* Low Quiescent Current: 20μA (Typical)
* At VOUT = 3.3V
- 100mA Output Current
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 i
