Designed to meet high-current requirements at high efficiency in
industrial and consumer applications; embedded core, memory, or logic
supplies; TVs, VCRs, and office or telecommunications equipment, the
SI-8050JD dc/dc step-down (buck) converter offers a constant 125 kHz
switching frequency essential for low EMI noise. The npn switch is
included on the die along with the oscillator, control, and logic circuitry
requiring only four external components for a regulated 5.0 V output at
up to 1.5 A. .
A wide input voltage range and integrated thermal and overcurrent
protection enhance overall system reliability. Reference accuracy and
excellent temperature characteristics are provided. An output-enable
input gives the designer complete control over power up, standby, or
power down.
This device is supplied in a 5-lead surface-mount plastic package
(TO-263) with ground tab to provide a low-resistance path for maximum
heat dissipation. A similar device in a flange-mounted (TO-220-style)
high-power package is the SI-8050JF.
