Description:

The GD30DC1801 is a user-friendly non-synchronousbuck converter, integrated with a 900mΩ low RDS_ONhigh-side MOSFET.It delivers up to 1A continuous output current, employingadvanced constant-on-time (COT) control for fasttransient response and simplified loop compensation.With a typical switching frequency of 460kHz, theGD30DC1801 helps reduce solution size and lowersBOM cost.The GD30DC1801 featuring a wide input voltage rangeof 4.5V to 100V, which accommodates a variety of stepdown applications.The GD30DC1801 built-in protection mechanismsinclude cycle-by-cycle current limit, hiccup-mode shortcircuit protection, and thermal shutdown to safeguardagainst excessive power dissipation.The GD30DC1801 comes in a cost-efficient SOT23-6package.
