System Regulator
with High Efficiency DC/DC Converters
BH6172GU
No.11032EAT04
●Descriptions
BH6172GU incorporates 1 DCDC+ 5 Linear LDO regulators. It is integrated in a small 2.6mm×2.6mm size package, with 16
steps adjustable Vo’s for every channel, low voltage output (0.8V~) to support almost any kind of mobile application now
available.
●Features
1) 1ch 500mA, high efficiency Step-down Converter. (16 steps adjustable VO by I²C)
2) 5-channel CMOS-type LDOs. (16 steps adjustable VO by I²C, 150mA×3, 300mA×2)
3) Power ON/OFF control enabled by I2C interface or external pin
4) I²C compatible Interface. (Device address is “1001111”)
5) Wafer Level CSP package(2.6mm×2.6mm) for space-constrained applications
6) Discharge resistance selectable for power-down sequence ramp speed control
7) Over-current protection in all LDO regulators
8) Over-current protection in Step-down Converter
9) Over-voltage protection in Step-down Converter
10) Thermal shutdown protection
●Applications
Mobile phones, Portable game systems, Portable mp3 players, Portable DVD players, Portable TV, Portable GPS,
PDA, Portable electronic dictionaries, etc.
●Absolute maximum ratings (Ta=25℃)
