g n i h tors c t i a Sw egul R Data Sheet 27469.302.1 SPI-8002TW Dual 1.5 A, DC/DC Step-Down 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 equipment, the SPI-8002TW 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. 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.
