特性 Features

• Single inductor 4-switch buck-boost controller

• On-the-fly bidirectional operation with independent

control of voltage and current on both ends

• Proprietary algorithm for smoothest mode transition

•MOSFET drivers with adaptive shoot-through

protection

•Wide input voltage range: 4.5V to 40V

•Wide output voltage range: 0.8V to 40V

• Supports pre-biased output with SR soft-start

• Programmable frequency: 100kHz to 600kHz

• Supports parallel operation current sharing with

cascade phase interleaving

• External sync with clock out or frequency dithering

• External bias for higher efficiency supports 5V - 36V

input
