Low Voltage Power
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 components, the SP6128A pack-
aged 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 300kHz,
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.
