Off-Line PWM Controllers with Integrated Power MOSFET
STR6A100xV/xVD Series
Data Sheet
Description
Package
DIP8
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
STR6A1××HVD
(1) (2)
(1) Frequency
M is 65 kHz.
H is 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
● Soft Start Function
● Adjustable Standby Operating Point
No Load Power Consumption < 15 mW
● Operation Mode
(2) OVP and TSD operation
D is auto-restart.
None is latched shutdown.

(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.
