Figure 13. Line Isolated Linear Regulator Charger
This application combines the MC33340/342 with an adjustable three terminal regulator to form an isolated secondary side battery charger. Regulator IC2 operates
as a constant current source with R7 setting the fast charge level. The trickle charge level is set by R5. The R2/R1 divider should be adjusted so that the Vsen input
is less than 2.0 V when the batteries are fully charged. The printed circuit board shown below will accept the several TO–220 style heatsinks for IC2 and are all
manufactured by AAVID Engineering Inc.
