Preliminary
uP6161
Single 12V Input Supply Dual Regulator Synchronous-Buck-PWM and Linear-Regulator Controller
General Description
The uP6161 integrates a high performance synchronousrectified buck controller and a linear-regulator controller.
This part works with a single +12V supply
voltage and delivers two high quality output
voltages for both processing unit and memory unit.
An internal linear regulator provides optimum 9V drive
voltage for efficiency and thermal management.
The buck controller features internal
MOSFET drivers that supports bootstrapped
voltage for high efficiency power conversion.
The bootstrap diode is built-in to simplify the circuit design and ...
