【文字介紹】

The RT6150A/B is a high efficiency, fixed frequency, Buck-Boost 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. Switchingfrequency is set at 1MHz to reduce the externalcomponent size. Quiescent current is only 60ua in Power Save Mode (PSM), maximizing battery life in portable applications. PSM operation is user controlled and can be enabled by driving the PS pin low. If the PS pin is driven high, then fixed frequency switching is enabled.

Other features include low shutdown current, internal, soft-start control, thermal shutdown protection and current limit. The RT6150A is available in the WDFN-10L 3x3
package and the RT6150B is available in the WDFN-10L 2.5x2.5 package.
