General 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 components are needed to complete the switcher design.
The ILC6390 automatically senses load variations to choose between 55% and 75% duty cycles.
Key Features
- 85% conversion efficiency at 50mA out Start-up voltages as low as 900mV ±2.5% accurate outputs Complete switch design with only 3 external components Automatically senses load variations to select the optimal duty cycle and extend conversion efficiency over a wide range.
- External transistor configuration to run as switcher controller.
- Shutdown to 0.5µA.
