STK740-480規(guī)格書詳情

Overview

The STK740-470 is a separate-excitation step-down chopper regulator hybrid IC for the secondstage circuit. This IC incorporates in the package all the necessary circuits for a chopper regulator including power switch, error amplifier, soft start, shutdown type output short protection, low-voltage malfunction prevention, on/off, and snubber circuits. Therefore, external components required are input and output capacitors and a choke coil only and this allows this IC to be used to construct a large-current (5A) chopper regulator as if a 3-pin regulator were used. DC8V to 18V input voltage can be handled and up to 5A of output current is supported.

Features

? Adoption of Sanyo IMST ; Insulated Metal Substrate Technology, allows the circuit to be operated without using a heat sink (see “No Fin Output Current Derating” chart in the page 6).

? Typical efficiency of 90 at DC 12V input, 2.5A output.

? Fine adjustment of output voltage enable.

? 50 kHz operating frequency.

? Low-RON resistance power MOSFET adopted.

? Low-VF Schottky barrier diode adopted.

Applications

? Local power supply for the equipment of which input rating is DC9V to 15V.
