Automotive, 36V, 1A, 500KHz current mode PWM controller with 16V and 10V UVLO 50% duty cycle

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.
