WHITE LED/OLED STEP-UP CONVERTER
FSP3304
FEATURES
Adjustable Output Voltage
Drives OLEDs or White LEDs
30V High Voltage Switch
1 MHz Switching Frequency
Tiny Inductors and Capacitors
Tiny SOT23-5L Package
GENERAL DESCRIPTION
The FSP3304 step-up DC/DC converter is optimized
for driving OLEDs or white LEDs. It can provide an
output voltage up to 24V. The device is capable of
driving up to seven LEDs in series from a Lithium-Ion
battery, with inherent current matching and uniform
brightness.
The FSP3304 incorporates a 30V high voltage switch.
The device operates at 1 MHz and allows the use of
few external components. The FSP3304 is available
in the tiny SOT23-5L package.

Descriptions
Switch Output. Connect this pin to the inductor and the Schottky diode. To
reduce EMI, minimize the PCB trace path between this pin and the input bypass
capacitor.
Ground.
Feedback Input. This pin is referenced to 1.24V.
Shutdown Control. Connect to a logic high to enable the device. Connect to a
logic low to disable the device. Never leave the pin unconnected.
Supply Input. Bypass to G with a capacitor of 1 µF or higher.
