BD9E151NUX-EVK-101: 5V @ 1.2A, 6 ~ 28V in

The BD9E151NUX-EVK-101 evaluation board has been specifically developed to evaluate the BD9E151NUX non-synchronous buck DC/DC converter with integrated 80mΩ high-side MOSFET. Features include wide input (6.0 to 28.0V) and output (1.0V to 23.0V) voltage ranges and a fixed operating frequency of 600kHz. Multiple protection functions are also built in, including a fixed soft start circuit that prevents inrush current during startup, UVLO (Under Voltage Lock Out), TSD (Thermal Shutdown), OCP (Over Current Protection), and OVP (Over Voltage Protection). An EN pin allows for simple ON/OFF control to reduce standby current.

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 0µA 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.
