4 Description
The MX5701 is a compact, PFM mode, and step-up DC-DC converter with low quiescent current, low-noise boost converters are intended for low-voltage systems that often need a locally generated high voltage. The internal synchronous rectifier reduces cost and PCB space by eliminating the need for an external Schottky diode. The duty cycle factor is automatically switched according to the load current.The start-up voltage is guaranteed below 1V.The APW7079 is suitable for portable battery-powered applications. Consuming low quiescent current and an optimized control scheme allows the device to operate at very high efficiency over the entire load current range.
