g n i h tors c t i a Sw egul R 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 stepdown (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. FEATURES ■ Wide 8 V to 50 V Input Range ■ Adjustable 1.2 V to 24 V Output Range ■ 3% Output Voltage Tolerance ■ To 3 A Output Current ■ Foldback Current Limiting ■ Constant 250 kHz Switching Frequency ■ 400 A Maximum Standby Current ■ 1.0 V Feedback Reference Voltage ■ Soft Start Avoids Supply Voltage Dip ■ Remote Voltage Sensing ■ Exposed Pad for Superior Heat Dissipation ■ Thermal Protection APPLICATIONS ■ TVs, VCRs, Electronic Games ■ Embedded Core, Memory, or Logic Supplies ■ Printers and Other Office Equipment ■ I……
