• Constant Current Source

The KB4313 step-up converter drives white LEDs

with a constant current to provide backlight in cell

phones, PDAs, and other hand-held devices. It

features allowing series connection of the white

LEDs so that the LED currents are identical for

uniform brightness. An enable input can be pulsed

repeatedly to adjust LED’s brightness. The fast 1.5

MHz current-mode PWM control allows for smaller

capacitor and inductor. Fault condition protection

uses

cycle-by-cycle

current

limiting

to

sense

maximum inductor current, thermal protection and

over-voltage protection. Also included soft-start

eliminates inrush current during start-up. The 0.2V

low reference voltage minimized the power loss

across the current-setting resistor.

The KB4313 is available in SOT23-6 packages
