Description:

The GD30DC1802 is a 100V/2A non-synchronous buckconverter with switch current limiting. Integrated with ahigh-side power MOSFET and employing an advancedconstant-on-time (COT) control scheme, it enables acompact solution size, superior load transientperformance, and excellent robustness.The integrated BST charging circuit further reduces costand solution footprint. The high-duty-cycle delay functionmakes this device particularly suitable for applicationsrequiring low dropout operation.With a quiescent current of 190μA for power savings anda low shutdown current of 3μA, it demonstratesexceptional battery-friendly performance.Featuring a wide input voltage range (4.5V to 100V) forversatile buck applications, the device maintains a mere3μA shutdown quiescent current.The GD30DC1802 is offered in the cost-optimizedESOP8 package format.
