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 components -
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.
GM3326 switches from PWM to PFM control during light loads, and the series offers high efficiencies from light loads through to large output currents.
Soft-start time is internally set to 10 msec, which offers protection against rush currents when the pow...
