ETA3300

24V, 1.5A 3MHz Boost Converte

FEATURES

DESCRIPTION

Up to 24V Output Voltage

The ETA3300 PFM 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 LEDs brightness. The fast

500KHz to 3MHz operation frequency allows for smaller

capacitor and inductor. Fault condition protection uses

cycle-by cycle current limiting to sense maximum inductor

current and over-voltage protection. The 0.2V low

reference voltage minimized the power loss across the

current sense resistor.

The converter can operate from 2V to 6V, and capable

of delivering maximum 200mA output current at 4-LEDs

application with 3V input voltage. Quiescent current drawn

from power source is as low as 120uA. All of these features

make ETA3300 be suitable for the portable devices, which

are supplied by a single battery.
