The UC1526A Series are improved-performance pulse-width modulator circuits intended for direct replacement of equivalent non- \x93A\x94 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. For ease of interfacing, all digital control ports are TTL compatible with active low logic.
Five volt (5V) operation is possible for \x93logic level\x94 applications by connecting VIN, VC and VREF to a precision 5V input supply. Consult factory for additional information.
