Product Overview
The <bold>ISL81601</bold> is a true bidirectional 4-switch synchronous buck-boost controller with peak and average current sensing and monitoring at both ends. Its wide input and output voltage ranges make it suitable for industrial, telecommunication, and after-market automotive applications. The ISL81601 uses the proprietary buck-boost control algorithm with valley current modulation for Boost mode and peak current modulation for Buck mode control.
- 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 60V
- Wide output voltage range: 0.8V to 60V
- 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 8V - 36V input
- Output and input current monitor
- Selectable PWM mode operation between PWM/DE/Burst modes
- Accurate EN/UVLO and PGOOD indicator
