Off-Line PWM Controllers with Integrated Power MOSFET
STR6A100HZ Series
Data Sheet
Description
Package
The STR6A100HZ series are power ICs for switching
power supplies, incorporating a MOSFET and a current
mode PWM controller IC.
DIP8
The operation mode is automatically changed, in
response to load, to the fixed switching frequency, to the
switching frequency control, and to the burst oscillation
mode. Thus the power efficiency is improved.
The product achieves high cost-performance power
supply systems with few external components.
Not to Scale.
STR6A100HZ Series
Features
Electrical Characteristics
fOSC(AVG) = 100 kHz
● Improving circuit efficiency (Since the step drive
control can keep VRM of secondary rectification
diodes low, the circuit efficiency can be improved by
low VF)
● Current Mode Type PWM Control
● Brown-In and Brown-Out Function
● No Load Power Consumption, PIN < 25mW
● Automatically changed operation mode in response to
load conditions
- Fixed switching frequency mode, 100 kHz (typ.) in
normal opetation.
- Green mode, 25 kHz (typ.) to 100 kHz (typ.) in
middle to light load.

● Bias Assist Function
* The output power is actual continues power that is measured at
50 °C ambient. The peak output power can be 120 to 140 % of the
value stated here. Core size, ON Duty, and thermal design affect the
output power. It may be less than the value stated here.
● Protections
- Two Types of Overcurrent Protection (OCP):
Pulse-by-Pulse, built-in compensation circuit to
minimize OCP point variation on AC input voltage
- Overload Protection with timer (OLP): Ato restart
- Overvoltage Protection (OVP): Latch shutdown
- Thermal Shutdown (TSD): Latch shutdown
