    摘要: A DC--DC converter having an input node receiving an input voltage V.sub.IN and generating an output voltage V.sub.OUT. A reference voltage generator provides a voltage V.sub.REF and a hysteresis voltage generator provides a voltage V.sub.HYST. A first comparator generates a signal determined from a difference between V.sub.REF and V.sub.OUT. A second comparator generates a signal determined from a difference between V.sub.OUT and V.sub.HYST. A latch is coupled to receive the outputs of the first and second comparators, and to generate an output. A driver circuit receives the latch output and generates a PWM signal used to switch the output stage. A double pulse suppression circuit masks off the latch inputs for a preselected time during the switching intervals fo the main power transistors to eliminate noise jitter.

    摘要: An optical coupler (10) and method of manufacturing the optical coupler (10) are disclosed. The optical coupler (10) includes a light emitter (12), a light detector (18, 22), an inner mold material (30), and a precision reflector (32) for efficiently reflecting light from the emitter (12) to the light detector (18, 22). In manufacturing the coupler (10), the light emitter (12) is coupled to a first mount lead (14) and the light detector (18) is coupled to a second mount lead (20). There may be more than one light emitter (12) or light detector (18,22). A transparent inner mold material (30) surrounds and encases the light emitter (12) and light detector (18) along with a portion of the first and second mount leads (14, 20) and forms a precision molded reflector (32) over the light emitter (12) and light detector (18). The precision molded reflector (32) may be a precision molded dome (38) or a precision molded multifaceted vault (44). The precision molded reflector (32) has a reflective coating (34) for returning light from the light emitter (12) to the light detector (18, 22). The light emitter (12), light detector (18, 22), a portion of the mount leads (14, 20), and the inner mold material (30) are encased by an opaque overmold (36).
