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

Download the ILC6391 datasheet PDF. This datasheet also covers the ILC6390 variant, as both devices belong to the same (ilc6390 / ilc6391) sot-89 step-up pfm switcher family and are provided as variant models within a single manufacturer datasheet.

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.

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.
