GL7201 - 1W High Power White LED Driver

General Description

The GL7201 is a step-up DC-DC converter that delivers a regulated output current.

The device switches at a 1.0MHz constant frequency, allowing for the use of small value external inductor and ceramic capacitors.

The GL7201 is targeted to be used for driving 1W white LED from a 0.9V to 3.2V input.

Key Features

Gleam Power Management GL7201 1W High Power White LED Driver Description The GL7201 is a step-up DC-DC converter that delivers a regulated output current. The device switches at a 1.0MHz constant frequency, allowing for the use of small value external inductor and ceramic capacitors. The GL7201 is targeted to be used for driving 1W white LED from a 0.9V to 3.2V input. The LED current can be programmed by the external current sense resistor, Rs, connected between the feedback pin (FB) and ground. A low 95mV feedback voltage reduces the power loss in the Rs for better efficiency. With its internal 2A, 100mΩ NMOS switch, the device can provide high efficiency even at heavy load.
