Overview
The ADP3654ARDZ, produced by Analog Devices Inc., is a high current and dual high-speed driver designed to drive two independent N-channel power MOSFETs. This driver uses an industry-standard footprint and offers high-speed switching performance, making it compatible with both analog and digital PWM controllers. It features a wide input voltage range of 4.5 V to 18 V, allowing it to be used in various power supply and motor drive applications. The ADP3654 is available in thermally enhanced SOIC_N_EP and MINI_SO_EP packaging, which maximizes high-frequency and high-current switching in a small PCB area.
