1 / 16 page TECHNICAL NOTE High-performance Regulator IC Series for PCs Ultra Low Dropout Linear Regulators for PC Chipsets BD3507HFV ● Description The BD3507HFV is suited for power supply for chipset bus. Though small in size, BD3507HFV adopts power PKG with radiation fins, and it therefore can be used for a regulator up to 550mA. Because it adopts Nch MOSFET and can form a ultra low dropout power supply of RON=300mΩ (TYP), BD3507HFV can compose a high-efficiency system, though it is of a linear type power supply. The output voltage can be set by VREF terminal and can be synchronized with other power supply. In addition, it can be used as a high side switch (RON = 300mΩ/lo = 550mA) of low-voltage power supply line. Because ceramic capacitors can be used for output capacitors, BD3507HFV contributes to downsizing and reduced thickness not only of IC but also of sets. ● Features 1) Built-in high-accuracy buffer circuit (can be set to 0.65-2.7V) 2) Adoption of ceramic capacitors 3) Built-in enable function (0μA at standby) 4) Built-in current limiting circuit (550mA Max) 5) Built-in undervoltage lockout circuit (UVLO) 6) Built-in thermal shutdown circuit (TSD) 7) Adoption of ultra-small-size high-power HVSOF6 package (3.0 x 1.6 x 0.75 mm) ● Applications Notebook PC, desktop PC, digital camera, digital home appliances Oct. 2008 |
