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-8003TW DC-to-DC step-down (buck) converter offers a variable 200 to 400 kHz switching frequency essential for small external components. The N-channel high-current 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.
