TPS61289 23VLOW , 25VHIGH, 20A Bidirectional BUCK/BOOST Converter
1 Features
3 Description
- VLOW voltage range: 0.5V to 23V
The TPS61289 is a bidirectional buck/boost
- The minimum VLOW voltage is determined by the VLOW/VHIGH ratio and frequency
- VHIGH voltage range: 4.5V to 25V
- Pin selectable bidirectional buck or boost mode
- Buck/boost forced PWM mode operation
- High efficiency and power capability
- Programmable current limit: 5A to 20A
- Integrated 8.5mΩ high-side MOSFET
- Switching frequency
- FSW 250kHz when VLOW > 1.7V
- FSW down to 100kHz when VLOW < 1.5V
- FSW down to 50kHz when VLOW < 0.5V
- 200mV hysteresis...
