AS7620 Datasheet (austriamicrosystems AG) - 500mA Hysteretic High Voltage Step-Down Converter

AS7620, 500mA Hysteretic High Voltage Step-Down Converter

The AS7620 is an easy-to-use, high-efficiency, highvoltage, 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
