DC/DC Converter IC offers fast transient times.

Model MB39A145, 2-channel DC/DC converter IC utilizes bottom detection comparator method that compares output voltage to reference voltage using high-speed comparator, minimizing variations in output voltage when load is high. Pulse Frequency Modulation function reduces power that is used during operation below 100 mA or in stand-by mode. Operating in temperatures from -30 to +85-
