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 V sen 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 heat-
sinks for IC2 and are all manufactured by AAVID Engineering Inc.
