wled flash light power supply requirements
wLED Flash Light Power Supply Requirements
  • Efficiency is of secondary order
    • Flash light supply is turned off for most of the time
  • Fast turn off and turn on times are required
    • Time period for flash ranges from 30ms up to 200ms
    • Rise time of current needs to be in the us range
    • Boost or charge pump must be powered up before the flash can be initiated
  • Storage capacitor and current limit might be required to avoid high input peak currents during flashing

Flash Light Solutions For Mobilephones

RGB LED

  • Usually darker then White LED
  • More complex control circuit required
    • Different forward voltages range from 2.4V to 4.1V due to the InGaN material being used
      • Boost converter or charge pump required
    • Special color mix required to achieve a white light
      • Different LED currents in each LED
      • Up to 30mA steady state
      • Up to 200mA peak current

White LED

  • 1 LED solution requires up to 700mA
    • Only a low voltage boost or charge pump converter with VOUT of up to 5V required
    • High input peak currents might cause problems in the application if no precautions are taken
  • 2 or more LEDs: I=30..100mA/LED
    • Low power LEDs are being used compared to the one chip/LED solution
    • Requires a high voltage boost converter running the LEDs in series
    • Using a charge pump requires running the LEDs in parallel

Charge Management

A charge management IC converts the DC input power to a voltage/current level need to quickly and safely charge a battery.

Battery Pack

The protection IC and the battery fuel gauge typically reside in the battery pack.

Protection IC

The protection IC ensure that a Li-Ion battery stays within safe voltage/current limits.

ProtectionIC

Battery Fuel Gauge

A battery fuel gauge measures current in and out of the battery and calculates the battery’s remaining energy.

Battery FuelGauge
