Low Noise High Efficiency
Step-down Switching Regulator
with Built-in Power MOSFET
BD8960NV
No.10027EBT21
âDescription
ROHMâs high efficiency step-down switching regulator BD8960NV is a power supply designed to produce a low voltage
including 1 volts from 5.5/3.3 volts power supply line. Offers high efficiency with synchronous rectifier. Employs a current
mode control system to provide faster transient response to sudden change in load.
âFeatures
1) Offers fast transient response with current mode PWM control system.
2) Offers highly efficiency for all load range with synchronous rectifier (Nch/Pch FET)
3) Incorporates soft-start function.
4) Incorporates thermal protection and ULVO functions.
5) Incorporates short-current protection circuit with time delay function.
6) Incorporates shutdown function
7) Employs small surface mount package : SON008V5060
âApplications
Power supply for LSI including DSP, Micro computer and ASIC
