OC5801L

OC5801L is a switched-step-down DC-DC controller that supports a wide range of input voltages and can exceed 150V input voltages. OC5801L features low standby power consumption, high efficiency, low ripple, and excellent bus voltage regulation and load regulation. It supports high current output, and the output current can be up to more than 10A.
OC5801L supports both output constant voltage and output constant current functions. The output constant current value can be set by setting the CS resistor. The output constant voltage value can be set by setting the voltage divider resistor on the FB1 and FB2 pins.
OC5801L is PWM controlled at a fixed frequency, with a typical switching frequency of 140KHz. The switching frequency is automatically reduced at light load to obtain high conversion efficiency.
The OC5801 integrates soft-start and over-temperature protection circuits, output short-circuit protection, current limit protection and other functions to improve system reliability.
OC5801L is available in a SOP8 package.
