The UC284xL-Q1 control device is an automotive-grade pin-for-pin compatible improved version of the UC284xAQ/UC284xA-Q1 families. Providing the necessary features to control current-mode or switched-mode power supplies, this device provides improved features: higher VCC range at 36V, lower start-up current at 0.25mA, tighter operating current tolerance at 15mA max, and faster response on cycle-by-cycle current protection at 100ns. Output driver of UC284xL-Q1 is improved with shorter rise and fall time at 75ns max to reduce switching loss, and stronger driver capabilities with lower output low level farther from the FETs threshold voltage.
