ISL81601FRZ-T7A

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
