LCW78_1.0 series
Wide Input Non-Isolated & Regulated, Single Output
Switching Regulator
500uA low quiescent current
at no load
100V surge withstand
Ultra wide 14:1 input voltage
range 5-72 VDC
Compatible with LM78
The LCW78_1.0 series is a non-isolated POL converter with an ultra wide
14:1 high input voltage range 5-72 VDC switching regulator with
standard SIP3 package, covering most of the battery ranges and the
standard power bus. This series with high efficiency and 500uA very
low quiescent current to be save the energy for the battery syetem
applications.
