PFC/DC-DC Systematic Combo Power IC STR-E1555 March, 2006 ■General Description ■Package---SLA21Pin STR-E1555 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-E1555 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 system with a small number of discrete components.
