Sanken STR6A161HZ
Off-Line PWM Controllers with Integrated Power MOSFET
STR6A100HZ Series
Data Sheet
Description
The STR6A100HZ series are power ICs for switching
power supplies, incorporating a MOSFET and a current
mode PWM controller IC.
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.
Features
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.
- Burst oscillation mode in light loat.
Random Switching Function
Slope Compensation Function
Leading Edge Blanking Function
Bias Assist Function
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

1. Absolute Maximum Ratings
Current polarities are defined as follows: a current flow going into the IC (sinking) is positive current (+); and a
current flow coming out of the IC (sourcing) is negative current ().
Unless specifically noted, TA = 25°C, 7 pin and 8 pin are shorted.
