Description

The EL7566 is a 6A capable buck regulator operating from an input voltage range of 3V to 6V. The duty cycle can be adjusted from 0% to 100% allowing for a wide range of programmable output voltages. Patented on-chip resistorless current-sensing ena bles current mode control for excellent step load response. Overcurrent, Overvoltage, input Undervoltage, and thermal protection is integrated along with soft-start and power-up sequencing features to produce an overall robust power solution for general purpose applications.
