STK740-441规格书详情
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.
