Off-Line Quasi-Resonant Switching Regulators
Features and Benefits
• TO–220F–7L package
• Lead (Pb) free compliance
• The built-in startup circuit reduces the number of external
components and lowers standby power consumption
• Multi-mode control allows high efficiency operation
across the full range of loads
• Auto burst oscillation mode for standby mode, for
improving low standby power at no load: input power
< 30 mW at 100 VAC and < 50 mW at 230 VAC
• Bottom-skip mode minimizes switching loss at medium to
low loads
Internal MOSFET VDSS(min) is 650 V
Internal MOSFET RDS(on)(max) 1.9 Ω (STR-Y6753) or
1.4 Ω (STR-Y6754)
• Built-in soft start function reduces stress applied to the
incorporated power MOSFET and peripheral components
• Step-on burst oscillation minimizes transformer
audible noise
• Built-in leading edge blanking (LEB) function eliminates

Package: 7-Pin TO-220F
Description
The STR-Y6753 and STR-Y6754 each comprise a power
MOSFET and a multi-functional monolithic integrated circuit
(MIC) controller designed for controlling switch mode power
supplies. The quasi-resonant mode of operation, coupled with
the bottom-skip function, allows high efficiency and low noise
at low to high operational levels, while burst oscillation mode
ensures minimum power consumption at standby.
In order to sustain low power consumption under low load and
in standby mode, the controller has built-in startup and standby
circuits. This enables output power for the STR-Y6753 up to
60 W with universal input or 100 W with a 380 VDC input,
and for the STR-Y6754 up to 67 W with universal input or
120 W with a 380 VDC input.
The compact 7-pin full mold package (TO220F-7L) reduces
board space by requiring a minimum of external components,
thus simplifying circuit design. This IC, including various
protection functions, is an excellent choice for standardized,
compact power supplies.

The NF pin (No. 7) should be connected
to the GND pin (No. 4), which should be
at a stable ground potential, to ensure
stability of operation.
