Power Management IC
BH6955GU
Description
BH6955GU is a Low noise Power Management IC for CPU application.
It contains step-down DC/DC converters and 6-LDOs, designed for portable devices. Each LDO can be operated by a
control input pin. The DC/DC converter output supplies power to a high-efficiency, low-noise, 1.5V LDO.
Features
1) DC/DC converter with fixed frequency (f=1.05MHz)
2) DC/DC converter switched to a high-efficient LDO regulator, for circuits with low current loads
3) Includes over current limiter
4) DC/DC converter with soft
-
start function
5) Includes five LDOs (REG1~5) with LCC (Low Current Consumption) mode
6) Small package
7) Includes TSD (Thermal Shut Down)
8) Includes UVLO (Under Voltage Lock Out protection)
Applications
The device is applicable to portable equipment, such as cellular phones, digital cameras, portable music players, portable
video games or PDAs.
