PAM2803 General Description

The PAM2803 is a set-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 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 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 1μA. The PAM2803 is available in the 6-lead TSOT26 package.
