Description:

The GD30DC1601-I is a 70V, 3A step-down converterwhich is Integrated high-side power MOSFET with180mΩ low resistance. Featuring constant on-time (COT)control, the GD30DC1601-I efficiently delivers up to 3Aof output 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, theGD30DC1601-I includes a cycle-by-cycle current limit,short-circuit protection with hiccup mode, FB openprotection, and thermal shutdown.The GD30DC1601-I is available with space savingESOP8 package.
