The EC1836 is a monolithic, step-down, switch mode converter with a built-in power MOSFET.
It achieves a 0.8A peak-output current over input supply 11V-80V 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 EC1836 requires a minimal number of readily-available external components.
The EC1836 is available in a SOT23-6 package.
