Off-Line PWM Controllers with Integrated Power MOSFET
STR6A100xV/xVD Series
Data Sheet
Description
The STR6A100xV/xVD series are power ICs for
switching power supplies, incorporating a MOSFET and
a current mode PWM controller IC.
The operating mode of the IC automatically changes
to green-mode or burst oscillation mode according to
load in order to improve the all load efficiency. 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
Soft Start Function
Adjustable Standby Operating Point
No Load Power Consumption < 15 mW
Operation Mode
Fixed Frequency: 65 kHz / 100 kHz
Green-Mode: 25 kHz to 65 kHz / 25 kHz to 100 kHz
Burst Oscillation Mode
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): Auto-restart
Overvoltage Protection (OVP): Latched shutdown or
auto-restart
Thermal Shutdown (TSD): Latched shutdown or auto-
restart*
*With hysteresis

(2) 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.
