The AN8018SA is a two-channel PWM DC-DC converter control IC that features low-voltage operation.
The document describes the AN8018SA, a two-channel PWM DC-DC converter control IC designed for low-voltage operation starting at 1.8 V. It supports generating step-up, step-down, or inverting output voltages using a minimal number of external components.
Key features include a wide operating supply voltage range from 1.8 V to 14 V, built-in short-circuit protection with a timer latch, and an under-voltage lock-out (U.V.L.O.) circuit. The IC incorporates high-precision reference voltages and allows for parallel operation of the two channels.
