The TPS61289 is a bidirectional buck/boost synchronous converter that integrates the high-side synchronous rectifier MOSFET and uses an external low side MOSFET. The TPS61289 can be configured as a buck or boost converter using the MODE pin. The TPS61289 can support 20A switching current and the VHIGH voltage supports up to 25V. The minimum VLOW voltage is determined by the VLOW/VHIGH ratio and frequency, for example, the VLOW voltage can support as low as 0.5V at the VHIGH = 15V condition. The device provides an excellent balance of efficiency, thermal dissipation and solution size for high power bidirectional conversion.

The TPS61289 offers adjustable switching current limit function. In addition, the device provides VHIGH overvoltage and undervoltage protection, cycle-by-cycle overcurrent protection, and thermal shutdown protection.

The TPS61289 offers a very small solution size with 2.5mm x 3.0mm VQFN HotRod™ Lite package with minimal external components.
