Data Sheet 27469.22 Sw Ritecghuilnagtors Step-Down to 3.3 V, 1.5 A, DC/DC Converter 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 telemunications equipment, the SI-8033JF dc/dc step-down (buck) converter offers a constant 125 k Hz 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 ponents for a regulated 3.3 V output at up to 1.5 A. A wide input voltage range and integrated thermal and overcurrent protection enhance overall system reliability. Reference accuracy and excellent temperature characteristics are provided. An output-enable input gives the designer plete control over power up, standby, or power down. This device is supplied in a fully molded TO-220-style 5-lead flange-mounted , high power, isolated plastic package. A similar device in a lower-power surface-mount plastic package is the...
