Push Pull Switching Regulator: Figure 12 shows the circuit configuration of push-pull switching regulator
that uses transformer. This system is suited for high power. Output transistors inside HA17524 can drive
external switching transistors.

Figure 12 Push-Pull Switching Regulator
Note
Compared with conventional series regulators, switching regulators generate high frequency noise by
switching current quickly. To reduce noise
1. As a general rule, insert line filter to reduce noise at the input.
2. To reduce noise at the output:
a. Twist output wiring together.
b. Do not bundle power source and output wiring.
c. Insert capacitor should be inserted at the load side.
d. Ground the power frame.
3. When choosing external parts (external switching transistor, diode, coil, etc) consider their capacitance
and characteristics.
