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).

摘要： A monolithic optical detector for determining spectral content of an incident light includes at least a first and second well in a substrate, the second well formed proximate the first well. The first well is configured to be exposed to incident light and for generating a first photocurrent as a function of the incident light. The second well is configured to be shielded from the incident light and for generating a second photocurrent as a function of the incident light. Lastly, a processing and control unit, responsive to the first and second photocurrents, determines an indication of spectral content of the incident light. A method and device parameter controller are also disclosed.
