The LX1681/1682 are monolithic, pulse-width modulator controller ICs.
They are designed to implement a flexible, low cost buck (step-down) regulator supply with minimal external components.
The LX1681 is a non-synchronouscontroller; the LX1682 has a synchronous driver for higher efficiency.
The output voltage is adjustable by means of a resistor divider to set the voltage between 1.25V and 4.5V.KEY
