Features, Applications

Buck and Boost Operation Including Seamless Transition between Buck and Boost Modes to 5.5V VIN Range to 5.14V VOUT with 20mV Step 3A Minimum Continuous Output Current (VINBB 3.0V, VOUTBB = 3.3V) Burst Current: 3.6A Minimum Output Current for 800s (VINBB 3.0V, VOUTBB = 3.3V)

The is a high-current, high-efficiency buck-boost regulator targeting single-cell Li-ion batterypowered applications. It supports a wide output voltage range from to 5.14V. The IC allows 5A (TYP) maximum switch current. In buck mode, the output current can go as high as 4A, and in boost mode, the maximum output current can 3A. A unique control algorithm allows high efficiency, outstanding line/load transient response, and seamless transition between buck and boost modes. The IC features I2C-compatible serial interface. The I2C interface allows the output voltage to be dynamically adjusted thus enabling finer control of system power consumption. The I2C interface also provides features such as enable control and device status monitoring. The multifunction GPIO pin is register settable to 5 different options such as FPWM mode enable and inductor peak current level selection. These options provide design flexibility that allows the IC to cover a wide range of applications and use cases.

Note 1: LXBB1/LXBB2 node has internal clamp diodes to PGNDBB and INBB. Applications that give forward bias to these diodes should ensure that the total power loss does not exceed the power dissipation limit of IC package.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Junction-to-Ambient Thermal Resistance (JA)..........55.49C/W Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
