Flash Light Solutions For Mobilephones

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

nning the LEDs in series Using a charge pump requires running the

LEDs in parallel

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

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

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

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