SP6128A Datasheet | Sipex

DESCRIPTION The SP6128A 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 ponents, the SP6128A packaged in an 14-pin TSSOP, is especially suited for low voltage applications where cost, small size and high efficiency are critical. The operating frequency is internally set to 300k Hz, allowing small inductor values and minimizing PC board space. The SP6128A drives two N-channel power MOSFETs for improved efficiency and includes an accurate 0.8V reference for low output voltage applications.
