Description

The UC2526AN is an improved-performance Pulse Width Modulation (PWM) features 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. It include the incorporation of a precision, band-gap reference generator, reduced overall supply current and the addition of thermal shutdown protection. It has the protective features of under-voltage lockout, soft-start, digital current limiting, double pulse suppression logic and adjustable dead time. For ease of interfacing, all digital control ports are TTL compatible with active low logic.
