The LX1681/1682 are monolithic, pulsewidth 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-synchronous controller; 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.
Supply Voltage (VC1) ............................................................................................ 18V
Supply Voltage (VCC) .............................................................................................. 7V
Output Drive Peak Current Source (500ns).......................................................... 1.0A
Output Drive Peak Current Sink (500ns) .............................................................. 1.0A
Input Voltage (SS/ENABLE Pin) .................................................................. -0.3V to 6V
Operating Junction Temperature ...................................................................... 150°C
Storage Temperature Range ........................................................... -65°C to +150°C
Lead Temperature (Soldering, 10 Seconds) ...................................................... 300°C
