PFC/DC-DC Systematic Combo Power IC
STR-E1565
General Description
STR-E1565 is a Hybrid IC power-factor-corrected switching mode power supply (SMPS). Start-up circuit and a controller of PFC and DC/DC parts are built in one chip. In addition, this chip and Power MOS FET for DC/DC part are incorporated into a SIP package thanks to High Voltage BCD Process technology. STR-E1565 includes the System of Prioritized PFC-Startup for prevention of Start-up Error. Our proprietary Multi Mode Control system simplifies the design www..comof High Efficiency and Low EMI power supply system with a small number of discrete components. Additionally, since built-in Auto Standby Function with AC input compensation reduces power consumption at standby, STR-E1565 is optimum for downsizing and standardization of power supply system. STR-E1565 enables to configure the optimum system for diverse PFC outputs because the power MOSFET is provided externally.

The maximum switching current is the Drain current determined by the drive voltage of the IC and threshold voltage (Vth) of MOS FET. Therefore, in the event that voltage drop occurs between No.17 and No.9 terminals due to patterning, the maximum switching current decreases as shown by V17-9 in Fig.1 Accordingly please use this device within the decrease value, referring to the derating curve of the maximum switching current.

CAUTION / WARNING
September .2005
Since reliability can be affected adversely by improper storage environment and handling methods during Characteristic tests, please observe the following cautions. Cautions for Storage
Ensure that storage conditions comply with the standard temperature (5 to 35C) and the standard relative humidity
(around 40 to 75%) and avoid storage locations that experience extreme changes in temperature or humidity.
Avoid locations where dust or harmful gases are present and avoid direct sunlight. www..com Reinspect for rust in leads and solderability that have been stored for a long time.
Cautions for characteristic Tests and Handling When characteristic tests are carried out during inspection testing and other standard tests periods, protect the devices from surge of power from the testing device, shorts between the devices and the heatsink. Remarks in using silicone grease for a heatsink When silicone grease is used in mounting this product on a heatsink, it shall be applied evenly and thinly. If more silicone grease than required is applied, it may produce forced stress. Volatile type silicone grease may produce cracks after elapse of long term, resulting in reducing heat radiation effect. Silicone grease with low consistency (hard grease) may cause cracks in the mold resin when screwing the product to a heatsink. Recommended operating temperature Inner frame temperature in operation TF=105 (C)MAX.
Recommended Screw Torque 0.588 to 0.785[]68[kgfcm] Soldering Temperature When soldering the products, please be sure to minimize the working time, within the following conditions.
2605C 3505C 10sec. 3sec. (Soldering iron
Considerations to protect the Products from Electrostatic Discharge
When handling the devices, operator must be grounded. Grounded wrist straps be worn and should have at least
1M of resistance near operators to ground to prevent shock hazard.
Workbenches where the devices 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 also be grounded. When soldering the devices, the head of a soldering iron or a solder bath must be grounded in other to prevent leak
voltage generated by them from being applied to the devices.
The devices should always be stored and transported in our shipping containers or conductive containers, or be
wrapped up in aluminum foil.
