The EC1688 is a monolithic, step‐ down, switch mode converter with a built‐ in power MOSFET.
It achieves a 2A peak‐ output current over input supply 9V‐ 60V with excellent load and line regulation.
Current‐ mode operation provides a fast transient response and eases loop stabilization.
Fault condition protections include cycle‐ by cycle current limiting and thermal shutdown.
The EC1688 requires a minimal number of readily‐ available external components. The EC1688 is available in a ESOP‐ 8 package.
