6.0V to 28V, 1.2A 1ch Step-Down Switching Regulator - BD9E151NUX

The BD9E151NUX is a 28V, 1.2A diode-rectification buck converter that integrated internal high-side 30V Power MOSFET. To increase efficiency at light loads, a pulse skipping is automatically activated. Furthermore, the 0uA shutdown supply current allows the device to be used in battery powered application. Current mode control with internal slope compensation simplifies the external component count while allowing the use of ceramic output capacitors.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
