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-8033JF 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 3.3 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 fully molded TO-220-style 5-lead
flange-mounted , high power, isolated plastic package. A similar device
in a lower-power surface-mount plastic package is the SI-8033JD.

■ Thermal Protection
APPLICATIONS
■ TVs, VCRs, Electronic Games
■ Embedded Core, Memory, or Logic Supplies
■ Printers and Other Office Equipment
■ Industrial Machinery
■ Telecommunications Equipment
