GM3326 Description
GM3326 is step-up/down DC/DC converter controller ICs with fast, and low ON resistance drivers built-in. A versatile step-up/ down DC/DC converter can be realised by using with large output current only 4 basic external ponents - transistors, coils, diodes, and capacitors. Output voltage is selectable in 0.1V steps within a 2.4V ~ 6.0V ( ± 2.5% accuracy) range, and switching frequency is set at or 300KHz.
