4. The total output power is 65W

5. The average conversion efficiency of full voltage is 5V=85.30%, 9V=89.72%, 12V=91.69%, 15V=93.04% and 20V=94.54%.

6. Output ripple ≤250mV

7. It has the functions of output over-current protection, short-circuit protection and over-temperature protection.

CX8901X is a high withstand voltage synchronous buck converter with an input voltage range of 10V-120V. CX8901X provides a large current of more than 10A.

CX8901X has the characteristics of low standby power consumption, high efficiency, low ripple, excellent bus voltage regulation rate and load regulation rate.

CX8901X can set the output constant voltage value by setting the voltage dividing resistor of FB pin.

CX8901X series adopts PWM control mode with fixed frequency, and the typical switching frequency is 100KHz. Under light load, it will enter the cycle skipping mode to obtain high conversion efficiency. The CX8901X series integrates the functions of soft start, over-temperature protection circuit, output short-circuit protection, current limiting protection and cycle-by-cycle current detection to improve the system reliability.

The CX8901X series is packaged in ESOP-8L and has a minimalist periphery, which is suitable for DC-DC buck applications with wide input and high power.

Features:

Enable pin turn-off to achieve zero power consumption

Wide voltage input range from 10V to 120V.
