Power IC for Quasi-Resonant Type Switching Power Supply
with High Efficiency, Low Noise and Low Standby Power in Full Load Range
STR-Y6453
Sep, 2013
◆General Descriptions
The STR-Y6453 is power IC for quasi-resonant
switching type power supplies, incorporating a power
MOSFET and a controller IC.
The product is automatically switched to the quasi
resonant operation, one bottom skip quasi resonant
operation and two bottom skip operation in normal
operation, and to the burst oscillation operation in light
load. That realizes the low standby power and a power
supply system with high cost performance, low external
part count can be easily composed.
◆Package
Package name: TO-220F-7L (FMS207)
◆Features
Multi operation mode
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 range
of loads.
Current mode control method
The built-in startup circuit reduces the power
consumption
Auto burst oscillation operation reduces dissipation.
Input power PIN ≤ 0.1W at no load
Standby input compensation
Overcurrent protection with AC input compensation
function
Built-in soft start function
Built-in maximum on-time limitation circuit
Built-in leading edge blanking function
Avalanche energy guaranteed; two-chip structure (enabling
the simplification of surge absorbing circuit)
Protection functions
Overcurrent protection (OCP) with input compensation
function: pulse by pulse basis, low dependence on input
voltage
Overload protection (OLP); latched shutdown or auto
restart
Overvoltage protection (OVP); latched shutdown
◆Application
Switching Power Supplies for
Digital appliance such as BD/DVD recorder, FPD TVs,
etc.
OA equipments such as printer
Home appliance (white goods)
Industry Machines
Communication Devices
◆Specification
MOSFET 650V, 1.8Ω(MAX)
◆Typical application circuit

Electrostatic Discharge
When handling the products, the operator must be grounded. Grounded wrist straps worn should have at least 1MΩ of
resistance from the operator to ground to prevent shock hazard, and it should be placed near the operator.
Workbenches where the products are handled should be grounded and be provided with conductive table and floor mats.
When using measuring equipment such as a curve tracer, the equipment should be grounded.
When soldering the products, the head of soldering irons or the solder bath must be grounded in order to prevent leak
voltages generated by them from being applied to the products.
The products should always be stored and transported in Sanken shipping containers or conductive containers, or be
wrapped in aluminum foil.
