500mA Hysteretic High Voltage Step-Down Converter With Dual Power Monitor

The AS7620 is an easy-to-use, high-efficiency, High-Voltage hysteretic Step-down DC-DC converter, operating in asynchronous mode. Its low-power architecture extends hold-up time in battery-backed and critical applications where maximum up-time over a wide input supply voltage range is needed, while still providing for high efficiencies of up to 90% at 12V during peak current demands. Although the AS7620 is optimized for 24V applications found in industrial and medical systems, its ability to support 100% Duty Cycle makes the AS7620 ideal for applications demanding maximum up-time and soft power fail behavior. In combination with low idle current of only 30A, on-demand switching reduces operating current at low load currents. By selecting an appropriate inductor value, operating current CAN be lowered and switching frequencies tuned to certain load conditions. A pin-strapped current limit input minimizes inductor peak current and thus inductor size and cost for any given application. The device further includes output short-circuit protection and thermal shutdown. In shutdown mode, only 1A (typ) of current is consumed.
