The UC1526A Series are improved-performance pulse-width modulator circuits intended for direct replacement of equivalent non- x93Ax94 versions in all applicaTIons. Higher frequency operaTIon has been enhanced by several significant improvements including: a more accurate oscillator with less minimum dead TIme, reduced circuit delays (parTIcularly in current limiting), and an improved output stage with negligible cross-conduction current. Additional improvements include the incorporation of a precision, band-gap reference generator, reduced overall supply current, and the addition of thermal shutdown protection.
Along with these improvements, the UC1526A Series retains the protective features of under-voltage lockout, soft-start, digital current limiting, double pulse suppression logic, and adjustable deadtime.
