3 Description

The TPS61230A device is a high efficiency fully integrated synchronous boost converter. It integrates 6-A, 21-mΩ and 18-mΩ power switches, which is capable of delivering up to 2.4-A output current at 5-V output with the 2.5-V input supply. The low RDS_ON switches enable the power conversion efficiency up to 96% and minimize the thermal stress in very compact solution size.

The typical operating frequency is 1.15 MHz, which allows the use of small inductor and capacitors to achieve a small solution size. The TPS61230A provides an adjustable output voltage via an external resistor divider.

During the light load condition, the TPS61230A automatically enters into the PFM operation for maximizing the efficiency with the lowest quiescent current. In the shutdown by pulling EN pin to the logic low, the load is completely disconnected from the input, and the input current consumption is reduced to below 1.0 μA.

When the output is shorted, the device enters into the hiccup protection mode and recovery automatically when the output short is released. Other features like the output over voltage protection, thermal shutdown protection are integrated.

The device is available in a 2.00-mm x 2.00-mm x 0.9-mm VQFN package and requires the minimum amount of external components.
