Description:

The GD30DC1602is a 65V, 5A step-down converterwhich is Integrated high-side power MOSFET with80mΩ low resistance. Featuring constant on-time (COT)control, the GD30DC1602efficiently delivers up to 5A ofoutput current while ensuring a rapid loop response.This device optimizes power conversion efficiencyacross various load conditions by reducing its switchingfrequency during light loads. This approach minimizesboth switching and gate driving losses.Equipped with essential protection mechanisms, theGD30DC1602 includes a cycle-by-cycle current limit,short-circuit protection with hiccup mode, FB openprotection, and thermal shutdown.The GD30DC1602 is available with space savingESOP8 package.
