BD8646FV
No.10027EAT44
●Description The BD8646FV is a synchronous step-down switching
regulator that integrates 2 low resistances N-channel MOSFETs. It achieves 2A continuous output current over a wide input supply range. Current mode operation provides fast transient response and easy phase compensation. ●Feature 1) Synchronous rectification with built-in FET type DC/DC converter 2) 2.0A output current 3) Range of operation power-supply voltage 4.5V～18V 4) Reference voltage FB 0.8V±1% 5) Programmable frequency 100kHz～600kHz 6) Over current protection function 7) Thermal shutdown function 8) Under voltage protection 9) Soft start time out function / Soft start delay circuit 10) Programmable OFFLATCH time ●Applications FPD,DVD,HDD Recorder,STB,Amusement,Other ●Absolute maximum rating (Ta=25℃) Parameter Input supply voltage BOOT terminal voltage EN terminal voltage Input terminal voltage SW terminal voltage Output current Power dissipation Operating temperature Storage temperature Symbol VIN VBOOT VEN VINP VSW IOUT Pd Topr Tstg
