3-MODES/ 3W WLED DRIVER WITH 1 OR 2 CELL BATTERY
The PAM2805 is a step-up DC-DC WLED driver with 3 modes cycling
function (100% brightness,25% brightness and 8.5Hz blinking).
The unique 3 modes cycling function can eliminate the needs of extra
functional MCU or IC.
The PAM2805 can deliver up to 750mA output current by setting an
The PAM2805 switches at a 1.0MHz constant frequency, allowing for
the use of small value external inductor and ceramic capacitors.
A low 95mV feedback voltage reduces the power loss in the RS for
better efficiency. With its internal 2A, 100mΩ device can provide high
efficiency even at heavy load.
The PAM2805 is available in TSOT26 package.
