Description:

(ilc6390 / ilc6391) sot-89 step-up pfm switcher.

ILC6390, (ILC6390 / ILC6391) SOT-89 Step-Up PFM Switcher

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.

Normal operation

ILC6390 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 efficien
