Description
The YB1510 is a step-up DC-DC converter; operates as current source to drive
up to 7 white LEDs 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 YB1510 switches at a fixed frequency of
700KHz, 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.
The YB1510 can drive up to 7 white LEDs from a single Li-Ion battery. The wide
input voltage range from 2.7V to 16V is ideal for portable and automotive
(5V/12V) applications with higher conversion efficiency. To control LED
brightness, the LED current can be pulsed by applying a PWM (pulse width
modulated) signal with a frequency range of 100Hz to 50KHz to the CTRL pin.
YB1510 has integrated Over Voltage Protection that prevents damage to the
device in case of a high impedance output due to faulty LED or open circuit
caused by abnormal conditions.
