3 Description
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-bycycle
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.
