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, 100

device can provide

high efficiency even at heavy load.

The PAM2805 is available in SOT23-6 package.
