ILC6391 Description
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 ponents are needed to plete the switcher design. The ILC6390 automatically senses load variations to choose between 55% and 75% duty cycles.
ILC6391 Key Features
- 85% conversion efficiency at 50mA out Start-up voltages as low as 900mV ±2.5% accurate outputs plete switch design with
- External transistor configuration to run as switcher controller
- Shutdown to 0.5µA
