RT6154B Datasheet High Efficiency Single Inductor Buck-boost Converter

Manufacturer: Richtek

Overview: ® RT6154A/B High Efficiency Single Inductor Buck-Boost Converter.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The RT6154A/B is a high efficiency single inductor BuckBoost Converter which can operate with wide input voltage such as battery which is higher or lower than the output voltage and it can supply the load current up to 4A.

The maximum peak current in the switches is limited to a typical value of 5A at VIN = 3.6V and 2.6A at VIN = 2.1V.

The RT6154A/B feedback loop is internally compensated for both Buck and Boost operation and it provides seamless transition between Buck and Boost modes and optimal transient response.

Key Features

  • Operates from a Single Li-ion Cell : 1.8V to 5.5V.
  • Adjustable Output Voltage : 1.8V to 5.5V.
  • 3A Maximum Load Capability for VIN > 3.6V, VOUT = 3.3V.
  • Power Save Mode (PSM) for Improving Low Output Power Efficiency.
  • Fixed Frequency Operation at 2.4MHz and Synchronization Possible from 2.2MHz to 2.6MHz.
  • Up to 96% Efficiency.
  • Input Current Limit.
  • Internal Compensation.
  • RoHS Compliant and Halogen Free.
