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. The ISL81601 has four independent control loops for input and output voltages and currents. Inherent peak current sensing at both ends and cycle-by-cycle current limit of this family of products ensures high operational reliability by providing instant current limit in fast transient conditions at either end and in both directions. It also has two current monitoring pins at both input and output to facilitate Constant Current (CC) limit and other system management functions. CC operation down to low voltages avoids any runaway condition at overload or short-circuit conditions.
In addition to multilayer overcurrent protection, it also provides full protection features such as OVP, UVP, OTP, and average and peak current limit on both input and output to ensure high reliability in both unidirectional and bidirectional operation. The IC is packaged in a space-conscious 32 Ld 5mm x 5mm QFN package or easy to assemble 4. 4mm x 9. 7mm 38 Ld HTSSOP package. Both packages use an EPAD to improve thermal dissipation and noise immunity. Low pin count, fewer external components, and default internal values make the ISL81601 an ideal solution for quick-to-market simple power supply designs. The unique DE/Burst mode at light-load dramatically lowers standby power consumption with consistent output ripple over different load levels.
