Intersil ISL6545
The ISL6545 makes simple work out of implementing a complete control and protection scheme for a DC/DC stepdown converter driving N-Channel MOSFETs in a synchronous buck topology. The ISL6545 integrates the control, gate drivers, output adjustment, monitoring and protection functions into a single 8 Ld SOIC or 10 Ld DFN package. The ISL6545 provides single feedback loop, voltage-mode control with fast transient response.| Part No. | ISL6545 |
