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 external resistor. 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.
