BD9641NUV

www.DataSheet4U.com Single-chip Type with Built-in FET Switching Regulator Series High-efficiency Step-up Switching Regulator with Built-in Power MOSFET BD9641NUV No.09027EAT27 ●Description BD9641NUV is synchronous rectification 1ch boost Switching converter built in Power MOS FET. Input voltage is 2.5V～5.5V. Low power consumption can be achieved. And, because Back-gate control function is built-in, the load can be isolated from the input without external FET in shutdown mode. ●Features 1) PWM synchronous rectification method 2) Input voltage is 2.5V～5.5V 3) Switching frequency is 900kHz. 4) Built in under voltage lockout function 5) Built in protection circuit(short-circuit protection,Thermal shutdown) 6) Built in back gate control function 7) Output voltage can be set by external resistance. 8) Built in power MOS FET transistor 9) Built in soft start function 10) VSON010V3030 package ●Application ・ For DSC/DVC motor ・ For cellular phone ・ For application using lithium cell ●Absolute maximum rating(Ta=25[℃]) Item Symbol Power-supply voltage VBAT Power Dissipation Pd Operating temperature range Topt Storage temperature range Tstg SW terminal current Isw Terminal allowable voltage VIN Junction temperature Tjmax ※1 ※2 Derating in done 5.6[mW/℃] for operating above Ta=25 [℃].
