1ch Step-Down Switching Regulator
BD906xx series
General Description
BD906xx 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 frequency with external resistor.
This switching regulator features a wide input voltage
range (3.5V to 36V, Absolute maximum 42V) and
operating temperature range (-40 °C to +125 °C).
Furthermore, an external synchronization input pin
enables synchronous operation with external clock.
