TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB7109F TB7109F Power supply IC for LNB The TB7109F is single chip power supply ICs for LNB that integrated buck DC-DC converter section utilizing a chopper circuit and series regulator section. The TB7109F contains high-speed P-channel MOSFETs for the high side main switch to achieve high efficiency. And series regulator section is fed into a overcurrent circuit of fold buck type, and it protects this product from the short circuit state of the load. Features • Output current: DC-DC Converter section IOUT1 = 500mA(max.) Series Regulator section IOUT2 = 400mA(max.) HSON8-P-0505-1.27 Weight: 0.068 g (typ.) • High efficiency: DC-DC Converter section η = 95% (typ.
