STCF04TBR Datasheet High Power White Led Supercap Driver

Manufacturer: STMicroelectronics

Overview: .DataSheet.co.kr STCF04 High power white LED SuperCap driver with I²C interface Data.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The STCF04 is a dedicated and space optimized high efficiency solution for driving a flash LED module in camera phones, PDAs and other handheld devices using the SuperCap technology.

It is based on a DC-DC buck-boost converter, which ensures proper and efficient charging control and monitoring of the SuperCap within the entire battery voltage range.

The output current control ensures good current regulation over the forward voltage spread characteristics of the flash LEDs in torch and flash mode operation.

Key Features

  • 1.8 MHz buck-boost converter with 1.2 A peak current limiting and synchronous rectification Programmable current limit Burst mode operation when output is charged Selectable 200 mA / 400 mA SuperCap charging current Input voltage range 2.7 V to 5.5 V Programmable output charging voltage up to 5.5 V Full I²C control Operation modes:.
  • Shutdown mode.
  • Monitoring mode with NTC and SuperCap monitoring.
  • Idle mode.
  • Flas.
