Overview
The NCP51530ADR2G, produced by ON Semiconductor, is a high-performance, high and low side gate driver designed for AC-DC power supplies and inverters. This device is optimized for high-frequency operations, offering best-in-class propagation delay, low quiescent current, and low switching current. It is available in two versions, NCP51530A and NCP51530B, with typical propagation delays of 60 ns and 25 ns, respectively. The NCP51530 is packaged in SOIC8 and DFN10 formats, with the SOIC8 package being pin-to-pin compatible with industry standard half-bridge ICs.
