Thick Film Hybrid IC
STK740-470
5V/5A Single Output Separate Excitation
Chopper Regulator
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.
