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 packaged 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. The SP6123 drives an all N-channel synchronous power MOSFET stage for improved efficiency and includes an accurate 0.8V reference for low output voltage applications.
