STK732C
Choke Coil L1
1. The inductance value shown in the test circuit diagram is for times when the current is zero, and therefore is a
reference value. Circuit operation should be checked in the actual mounted configuration of the final product.
2. The inductor L1 should be a product that can handle the high frequencies used in a switching power supply.
3. Be sure to use an inductor with appropriate rated current and magnetic saturation specifications.
Current Detection Resistor Rs1
1. Since this resistor carries large currents, its power dissipation must be taken into consideration.
2. Manufacturing variations in the resistor value can change the overcurrent protection circuit’s operating point.
Two Output Power Supply Structural Example (connecting to an STK730)
Note: It is possible for STK730 input ripple currents to cause L1 to vibrate audibly and adversely influence the 15 V system. If such problems occur, an
inductor can be inserted at the point marked with dotted lines in the figure to form an LC filter.
Caution: Step down chopper power supplies can generate an overvoltage on the output side equivalent to the input
voltage if there is an assembly error on the PC board or if the IC fails. Therefore we strongly recommend the
use of a crowbar or other overvoltage protection circuit in power supply designs.
