Коммутационные контроллеры UC2526ADW

Регулирующий ШИМ , 35В-7В питание, 600кГц, 5.05В/100мА выход, SOIC-18

The UC2526ADW is an improved-performance Pulse Width Modulation (PWM) intended 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, it retains 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.
