LM3554 datasheet

Description :

The LM3554 is a 2MHz fixed frequency, current mode synchronous boost converter. The device is
designed to operate as a dual 600mA (1.2A total) constant-current driver for high-current white LEDs, or as a regulated 4.5V or 5V voltage source.

The dual high-side current sources allow for grounded cathode LED operation. An adaptive regulation method ensures the current source for each LED remains in regulation and maximizes efficiency.
