PAM2803
3W HIGH POWER WHITE LED DRIVER
Description
The PAM2803 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.
Pin Assignments
The PAM2803 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 ...
