ISL81801 - 80V Bidirectional 4-Switch Synchronous Buck-Boost Controller

Datasheet Summary

Description

.

.

.

Features

  • such as OVP, UVP, OTP, 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 x5mm TQFN package or easy to assemble 4.4mmx9.7mm 38 LD HTSSOP package. Both packages use an EPAD to improve thermal performance and noise immunity. Low pin count, fewer external components, and default internal values make the ISL81801 an ideal solution for time to market simple power suppl.

Datasheet ISL81801 80V Bidirectional 4-Switch Synchronous Buck-Boost Controller The ISL81801 is a true bidirectional 4-switch synchronous buck-boost controller with peak and average current sensing and monitoring at both ends. With wide input and output voltage ranges, the controller is suitable for industrial, telecommunication, and after-market automotive applications. The ISL81801 uses a proprietary buck-boost control algorithm with valley current modulation for Boost mode and peak current modulation for Buck mode control. The ISL81801 has four independent control loops for input and output voltages and currents.
