GENERAL DESCRIPTION

The FSP3302/FSP3303 are high performance, white

LED bias generators for systems consisting of multiple

white LEDs. The FSP3302/FSP3303 are identical

except for the number of LEDs they drive; FSP3302

supports up to four LEDs, while FSP3303 can supply up

to six LEDs.

These devices integrate proprietary constant-frequency

charge

pump

circuitry

that

includes

automatic

mode-switching to maximize efficiency with accurate,

matched current sources that drive the white LEDs.

Current matching is better than 0.3%, resulting in highly

uniform brightness across different LED channels.

The FSP3302/FSP3303 feature adjustable LED bias

currents, which are programmable through a simple

serial interface. Charge pump operation at 1.2MHz

allows the use of small capacitors and minimizes ripple.

The devices also feature soft-start circuitry to limit

inrush current during startup, and thermal shutdown

protection.

The FSP3302/FSP3303 are available in space saving

QFN16L and µQFN16L packages.
