Exar XRP7657 Non-Synchronous Step Down Converter
The Exar XRP7657 non-synchronous voltage mode PWM step down (buck) converter can provide a constant output current up to 2A and offers a wide 4.75V to 25V input voltage range that allows for single supply operations from industry standard 5V, 12V, and 24V power rails. The XRP7657 step down converter reduces overall component count and solution footprint with a 420 kHz constant operating frequency and integrated high side switch. This Exar device features 2% output setpoint accuracy, high efficiency, low ripple, and excellent line and load regulation. The enable function and soft start feature of the XRP7657 allow for controlled power up sequencing implementation. This Exar step down converter is ideal for use in distributed power architectures, point of load converters, and audio-video and medical equipment.
