Полупроводники - Микросхемы\Микросхемы Управления Питанием\DC - DC Устройства Управления Питанием\DC - DC Контроллеры The ISL81601 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
