Designed to meet high-current requirements at high efficiency in industrial and consumer applications; embedded core, memory, or logic supplies; TVs, VCRs, and office or telecommunications equipment, the SI-8050JD dc/dc step-down (buck) converter offers a constant 125 kHz switching frequency essential for low EMI noise. The npn switch is included on the die along with the oscillator, control, and logic circuitry requiring only four external components for a regulated 5.0 V output at

up to 1.5 A. .
