DESCRIPTION  
The SP6123 is a fixed frequency, voltage mode, synchronous PWM controller designed to  
work from a single 5V or 3.3V input supply, providing excellent AC and DC regulation for high  
efficiency power conversion. Requiring only few external components, the SP6123 pack-  
aged in an 8-pin NSOIC, is especially suited for low voltage applications where cost, small  
size and high efficiency are critical. The operating frequency is internally set to 300kHz  
(SP6123) or 500kHz (SP6123A), allowing small inductor values and minimizing PC board  
space. TheSP6123drivesanallN-channelsynchronouspowerMOSFETstageforimproved  
efficiency and includes an accurate 0.8V reference for low output voltage applications.
