The UC1526A Series are improved-performance pulse-width modulator circuits intended for direct replacement of equivalent non-“A” versions in all applications.
The UNITRODE UC1526A Series are improved-performance pulse-width modulator circuits intended for direct replacement of equivalent non-"A" versions. Key enhancements include a more accurate oscillator with less minimum dead time, reduced circuit delays, and an improved output stage with negligible cross-conduction current. The series also incorporates a precision band-gap reference generator and thermal shutdown protection.
