austriamicrosystems has expanded its DC-DC converter portfolio with the AS7620, an hysteretic, high efficiency 32 V step-down regulator in a small 4 x 4 mm MLPQ 12-pin package. Ideally suited to maximise up-time of utility metering, sensor interface and other industrial motion control and battery-powered data-acquisition equipment, the device provides both early-power-fail warning and power-good signals to microcontrollers that cannot afford to lose critical data during a power failure or brown-out condition.
The AS7620 is optimised for industrial 24 V applications and delivers up to 500 mA. Available with a fixed 3,3 V output or adjustable output voltage between 1,2 V and VIN, the device features a wide input voltage between 3,6 V and 32 V and offers a high efficiency rate of up to 93%. Additionally, an integrated 100% duty-cycle extends operation in low-dropout conditions. A pin-selectable peak current limit optimises inductor selection, reducing component size.
Built on an hysteretic architecture, the AS7620 is a power miser when it comes to minimum and partial load operation, operating on less than 37 μA when delivering 500 μA of output current and consuming approximately 100 μA at 10 mA output, which allows for smaller hold-up capacitors or extends operating battery life for portable analysers.
The AS7620 allows a wide range of low profile inductors and ceramic capacitors and does not require any compensation. Soft-start, current limit and thermal shutdown make the converter failsafe. During shutdown the current draw is reduced to only 1 μA. It is available for the industrial temperature range of -40°C to +85°C.
