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.
