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
