SI-8025JF

Step-Down to 2.5 V, 1.5 A, DC/DC 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 or telecommunications equipment, the

SI-8025JF 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 2.5 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

powerdown.

This device is supplied in a fully molded TO-220-style 5-lead

flange-mounted , high power, isolated plastic package.
