*
*
* 85% conversion efficiency at 50mA out Start-up voltages as low as 900mV ±2.5% accurate outputs Complete switch design with only 3 external c.
In addition, the ILC6391 is configured to drive an external transistor to achieve higher power levels.
Applications
50 mA boost converter using Pulse Frequency Modulation, or PFM, technique, in 5-lead SOT-89 or a 5-lead SOT-23 package. Only 3 external components are needed to complete the switcher design. The ILC6390 automatically senses load variations to choose .
