RT6150B-33GQW

The RT6150B-33GQW from Richtek is a current mode buck-boost converter in 10 pin WDFN 2.5x2.5 package. It is a high efficiency, fixed frequency, fixed 3.3V buck-boost DC/DC converter. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making it 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 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.

• Input voltage range from 1.8V to 5.5V
• Fixed frequency operation with battery voltages
• Synchronous rectification up to 90% efficiency
• Up to 800mA continuous output current
• VOUT disconnected from VIN during shutdown
• Less than 1μA shutdown current
