Datasheet  
Input Voltage 3.5 V to 36 V  
Output SW Current 4 A / 2.5A / 1.25A  
1ch Step-Down Switching Regulator  
BD906xx-C series  
General Description  
Key Specifications  
BD906xx-C series is a step-down switching regulator  
with integrated POWER MOS FET and have the  
capability to withstand high input voltage, providing a free  
setting function of operating switching frequency with  
external resistor. This switching regulator features a wide  
input voltage range (3.5 V to 36 V, Absolute maximum 42  
V) and operating temperature range (-40 °C to +125 °C).  
Furthermore, an external synchronization input pin  
enables synchronous operation with external clock.
