GM3326 Datasheet (Gamma Microelectronics) - STEP-UP & DOWN DC/DC CONVERTER CONTROLLER ICS

GM3326, STEP-UP & DOWN DC/DC CONVERTER CONTROLLER ICS

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 components - transistors, coils, diodes, and capacitors.

Output voltage is selec
