Additional Infomation About Product

Datasheet 6.0V28V, 1.2A 1ch 1ch Step-Down Switching Regulator BD9E151NUX Key Specifications General Description Input Voltage 628 V The BD9E151NUX is a 28V, 1.2A diode-rectification Ref. Precision (Ta=25) 1.0 % buck converter that integrated internal high-side 30V Max Output Current 1.2 A (Max.) Power MOSFET. To increase efficiency at light loads, a Operating Temperature -40~85 pulse skipping is automatically activated. Furthermore, the 0uA shutdown supply current allows the device to be used in battery powered application. Current mode Packages control with internal slope compensation simplifies the VSON008X2030 2.00mm x3.00mm x 0.60mm external component count while allowing the use of ceramic output capacitors.
