MAX868 Regulated, Adjustable -2x Inverting Charge Pump General Description
... The MAX868 inverting charge pump uses pulsefrequency-modulation (PFM) control to generate a regulated negative output voltage up to -2 x V IN. PFM operation is obtained by enabling the internal 450kHz oscillator as needed to maintain output voltage regulation. This control scheme reduces supply curr ...
