STRE1565

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 of High Efficiency and Low EMI power supply www.DataSheet4U.com 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.
