BD9528MUV - Rohm

BD9528MUV Main Power Supply ICs

BD9528MUV is a 2ch switching regulator controller with high output current which can achieve low output voltage (1.0V～ 5.5V) from a wide input voltage range (5.5V～28V). High efficiency for the switching regulator can be realized by utilizing an external N-MOSFET power transistor. A new technology called H3RegTM(High speed, High efficiency, High performance) .
