ARG81800 40V 500mA / 1.0A Synchronous Buck Regulators

TheARG81800 includes all the control and protection circuitry to produce a PWM regulator with ±1.5% output voltage accuracy, with ultralow quiescent current to enable “keepalive” supply operation with minimal current draw from the supply during very light load regulation. There are two versions of t.
