Figure 15. Line Isolated Switch Mode Charger
The MC33340/342 can be combined with any of the devices in the UC3842 family of current mode controllers to form a switch mode battery charger. In this example,
optocouplers OC1 and OC2 are used to provide isolated control signals to the UC3842. During battery voltage sensing, OC2 momentarily grounds the
Output/Compensation pin, effectively turning off the charger. When fast charge termination is reached, OC1 turns on, and grounds the lower side of R3. This reduces
the peak switch current threshold of the Current Sense Comparator to a programmed trickle current level. For additional converter design information, refer to the
UC3842 and UC3844 device family data sheets.
