Buck/Boost Regulating Charge Pump in µMAX
General Description
The MAX1759 is a buck/boost regulating charge pump that generates a regulated output voltage from a single lithium-ion (Li+) cell, or two or three NiMH or alkaline cells for small hand-held portable equipment.
The MAX1759 operates over a wide +1.
6V to +5.
5V input voltage range and generates a fixed 3.
3V or adjustable (2.
5V to 5.
5V) output (Dual Mode™).
Maxim’s unique charge-pump architecture allows the input voltage to be higher or lower than the regulated output voltage.
Despite its high 1.
5MHz operating frequency, the MAX1759 maintains low 50µA quiescent supply current.
Designed to be an extremely compact b...
