The EC1837 is a high frequency step-down switching regulator with integrated internal highside high voltage power
It provides 2A output with current mode control for fast loop response and easy compensation.
The wide 12V to 80V input range accommodates a variety of step-down applications, including those in automotive input environment.
A 1μA shutdown mode supply current allows use in battery-powered applications.
High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition to reduce the switching and gate driving losses.
The frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation.
The EC1837 is available in ESOP8 package.
