Description
The YB1518 is a step-up DC-DC converter; operates as current source to drive
up to 6 white LEDs(VIN at 3.0V) or 8 LEDs(VIN at 3.5V) or 9 LEDs(VIN at 3.5V)
in series. Series connecting of the LEDs provides identical LED currents
resulting in uniform brightness and eliminating the need for ballast
resistors. The light intensity of these LEDs is proportional to the current
passing through them. The YB1518 switches at a fixed frequency of ~930KHz,
allowing the use of tiny, low profile inductors and capacitors to minimize
footprint and cost in space consideration applications for cellular phone
backlighting or other hand
held equipment.
