Product Overview
TPS61230 is a Texas Instruments synchronous step-up converter for Power_Management designs that need an adjustable boosted output. It operates from a recommended 2.3 to 5.5 V VIN pin range and provides a 2.5 to 5.5 V output range. The converter reaches up to 96% efficiency and can deliver up to 2.1 A for a 5 V output from a 3.3 V input supply.
The device integrates a 5 A internal switch and operates at a typical 2 MHz switching frequency. Control and monitoring functions include automatic power-save mode at light load, load disconnect during shutdown, an open-drain PG output, and an SS pin for programmable soft start with an external capacitor.
Assembly uses the 11-pin VSON (DRC) package with a 3.00 mm x 3.00 mm x 0.9 mm body. Thermal data for this package includes 49.1 °C/W junction-to-ambient resistance and 4.5 °C/W junction-to-case bottom resistance. Applications should observe the -40 to 125 °C recommended operating junction range and absolute maximum pin voltage limits of -0.3 to 7 V.
