Product Summary

The NCP1580DR2G is a voltage mode PWM controller designed to operate from a 5.0 V or 12 V supply and produce an output voltage as low as 0.8 V. This 8.pin device provides an optimal level of integration to reduce size and cost of the power supply. The NCP1580DR2G has a fixed 350 kHz oscillator and soft.start function. The NCP1580DR2G provides a 1.5 A floating gate driver design to drive N.Channel MOSFET in a synchronous configuration. Adaptive non overlap circuitry reduces switching losses by preventing simultaneous conduction of both outputs. Protection features include thermal shutdown and undervoltage lockout (UVLO). The NCP1580DR2 is available in an 8.pin SOIC package. The applications of the NCP1580DR2G include Graphics Cards, Desktop Computers, Servers/Networking, DSP and FPGA Power Supply, DC-DC Regulator Modules.
