Description
The RT6154A/B is a high efficiency single inductor BuckBoost Converter which can operate with wide input voltagesuch as battery which is higher or lower than the outputvoltage and it can supply the load current up to 4A. Themaximum peak current in the switches is limited to atypical value of 5A at VIN = 3.6V and 2.6A at VIN = 2.1V.The RT6154A/B feedback loop is internally compensatedfor both Buck and Boost operation and it provides seamlesstransition between Buck and Boost modes and optimaltransient response. The RT6154A/B operates at 2.4MHztypical switching frequency in full synchronous operation.The RT6154A/B operates in Pulse Skipped Modulation(PSM) mode for increasing efficiency during low powerRF transmission modes. The Power Save Mode can bedisabled, forcing the RT6154A/B to operate at a fixedswitching frequency operation at 2.4MHz. The RT6154A/B can also be synchronized with external frequency from2.2MHz to 2.6MHz. The RT6154A output voltage isprogrammable using an external resistor divider, and theRT6154B is fixed internally to 3.3V.
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% fficiency
●Input Current Limit
●Intermnal Compensation
●RoHS Compliant and Halogen Free
Applications
●Cellular Phones
●Portable Hard Disk Drives
●PDAs
