GENERAL DESCRIPTION

The FSP3604 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 FSP3604 is targeted to be used for driving loads

up to 1A from a two-cell alkaline battery. 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. During

the shutdown mode, the feedback resistor Rs and the

load are completely disconnected and the current

consumption is reduced to less than 1uA.
