STR-L6400 Series
Power IC for Quasi-Resonant Type Switching Power Supply
with High Efficiency, Low Noise and Low Standby Power
in Full Load Range
Low-Height and Enough Creepage Isolation (>6mm)
between High and Low Voltage Terminals
■
General Descriptions
The STR-L6400 series products are power ICs for quasi-resonant switching type power
supplies, incorporating a power MOSFET and a controller IC. The product achieves high
efficiency and low noise power supply systems across the full load range, by the low standby
power, the quasi-resonant operation, the bottom-skip quasi-resonant operation, and the
burst-oscillation. The product is recommended for the systems requiring low-height and enough
clearance and creepage isolation between high and low voltage terminals.
The STR-Y6400 series products are the different package (TO-220F) versions.

Features
ꢀ
Multi-Mode Control
The operation mode switching with four steps according to load conditions achieves the optimal high efficiency and
low noise power supply systems across the full load range.
・In Standby: Auto Standby (Auto Burst-Oscillation)
・Under Low to Middle Load Conditions: 1 or 2 Bottom-Skip Quasi-Resonant Operation (Bottom-Skip QR)
・Under Middle to Rating (or Heavy) Load Conditions: Quasi-Resonant Operation (QR)
Current-Mode Control
Bottom-Skip Function with Delay Time Setting, enabling stable switching
Built-in Startup Circuit, enabling low power consumption
Auto-Standby Function with Burst-Oscillation, enabling low standby power(Input power PIN < 100mW at no load)
Soft-ON Function, preventing the audible noise from transformer, during the standby operation (burst-oscillation)
and the dynamic load change.

Note 1: The maximum output power is derived from thermal specifications. The actual output power may be available
around 120 –140% of the above values, respectively, but may be limited by ON duty setting on transformer
design or lower output voltage.
Note 2: The condition of the maximum output power is “without heat sink”.
