The MP5418A is a monolithic negative charge pump with a built-in adjustable negative regulator. It has a 2.3V to 5V input range, and provides an unregulated output that equals negative input voltage. The MP5418A also provides a regulated output between 0V and negative input voltage.

No external inductor is required for simplicity and compactness. An internal soft-start circuit effectively reduces the inrush current during start-up.

The MP5418A is available in an ultra-low profile QFN-10 (1.4mmx1.8mm) package. The MP5418A requires four ceramic capacitors to get the minimum solution size. It is ideal for a wide range of applications, including optical modules, RF amplifiers, and sensor supplies.
