Thick Film Hybrid IC 5V/5A Single Output Separate Excitation Chopper Regulator Ordering number:EN*6107 STK740-470 SANYO Electric Co.,Ltd. Semiconductor Company TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN 63099RM (KT) No.6107–1/10 1 12 46.6 41.2 (6.63) 11 ×2.54=27.94 3.6 0.5 2.54 8.5 0.4 2.9 Package Dimensions unit:mm 4170-SIP28 [STK740-470] SANYO : SIP-28 Preliminary 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 regula- tor were used. DC8V to 18V input voltage can be handled and up to 5A of output current is supported. Applications • Local power supply for the equipment of which input rating is DC9V to 15V. 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 Derat- ing” 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. |
