BD95710MUV is a dual-phase switching regulator controller with high output current which can achieve low output voltage (0.4V ~

3.3V) from AC/DC 5V or 12V. High efficiency for the switching regulator can be realized by utilizing an external N-MOSFET power

transistor. A new technology called H

load change without phase compensation capacitance and resistance. For various applications, it is available to select the 3 types

of N-MOSFET gate drive voltage (12V: for drive ability, 8V: for intermediate drive ability, 5V: for small real estate).
