RT6150A/B
Current Mode Buck-Boost Converter
General Description
The RT6150A/B is a high efficiency, fixed frequency, BuckBoost DC/DC converter that operates from input
voltages above, below or equal to the output
voltage.
The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for single lithium-ion, multi-cell alkaline or Ni-MH battery applications where the output
voltage is within the battery
voltage range.
The device includes two N-
MOSFET switches and two P
MOSFET switches for high efficiency operation.
Switching frequency is set at 1MHz to reduce the external component size.
Quiescent current is only 60μA in Po...
