SG1577SY
IC CTLR DC-DC DUAL SYNCH 20-SOIC
SG1577
The SG1577 is a high-efficiency, voltage-mode, dual-channel, synchronous DC/DC PWM controller for two independent outputs. The two channels are operated out of phase. The internal reference voltage is trimmed to 0.7V?1.5%.The SG1577is connected to the error ...
SG1549
This SG1549 is an analog latch device with digital reset. SG1549 was specifically designed to provide pulse-by-pulse current limiting for switch-mode power supply systems, but many other application are also feasible. Its function is to provide a latching sw...
SG1548
The SG1548 is an integrated circuit capable of monitoring up to four positive DC supply voltages simultaneously for overvoltage and undervoltage fault conditions. An on-chip inverting op amp also allows monitoring one negative DC voltage. The SG1548 is accur...
SG1544
The SG1544was designed to provide all the operational features of the SG1543/ 2543/3543 devices but with the added advantage of uncommitted inputs to the voltage sensing comparators. This allows monitoring of voltage levels less than 2.5 volts by dividing do...
SG1543
The SG1543contains all the functions necessary to monitor and control the output of a sophisticated power supply system. Over-voltage (O.V.) sensing with provision to trigger an external SCR "crowbar" shutdown; an under-voltage (U.V.) circuit which can be us...
