SPI-8010A
3 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-8010A dc/dc step-
down (buck) converter offers a constant 250 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.
