SPI-8001TW General Description
Designed to meet high-current requirements at high efficiency in industrial and consumer applications; embedded core, memory, or logic supplies; TVs, VCRs, and office equipment, the SPI-8001TW dc/dc step-down (buck) converter offers a constant 250 kHz switching frequency essential for small external components. The n-channel highcurrent FET is included on the die along with the oscillator, control, and logic circuitry.
A wide input voltage range and integrated thermal and overcurrent protection enhance overall system reliability. Reference accuracy and excellent temperature characteristics are provided. A chip-enable input gives the designer complete control over power up, standby, or power down. A similar device, with increased input and output voltage ratings, is the SPI-8002TW.
This device is supplied in a 16-lead surface-mount plastic SOIC with exposed pad to provide a low-resistance path for maximum power dissipation, low junction temperature, and improved reliability.
