MOTOROLA ANALOG IC DEVICE DATA
NOTE: An excessive load induced voltage across R S can occur if either the source input or load output is shorted. This voltage can
NOTE: Multiple outputs can be controlled by summing the error signal into a common optoisolator. The converter output with the largest

can be used in any of the MC33341 applications where high peak currents are anticipated.
