DC/DC Asynchronous Buck Converter
V5501 is a high frequency, asynchronous, stabilize voltage chip which is integrated with 450mA peak-current, 40V MOSFET endurance which can transmit 300mA output current. V5501 complies with self-adaptive shutdown PWM mode to control and adjust the output voltage. The 2MHz switch frequency of V5501 can reduce the voltage ripple, external inductance, and the size of capacitance.

Input voltage range: 5~40V
2MHz switch frequency 
Support self-adaptive timing shutdown (PWM)
