The Diodes Incorporated AP63300WU-7 is a 3A synchronous buck converter designed for step-down DC-DC conversion. It operates with an input voltage range from 3.8V to 32V and features integrated high-side (75mΩ) and low-side (40mΩ) power MOSFETs for high efficiency.
This device utilizes peak current mode control and an integrated loop compensation network, minimizing external component count. Its design is optimized for Electromagnetic Interference (EMI) reduction through a proprietary gate driver scheme that resists switching node ringing without sacrificing switching times. The AP63300 variant also includes Frequency Spread Spectrum (FSS) with ±6% jitter to further reduce EMI.
Key electrical specifications include a 500kHz switching frequency, a low quiescent current of 22µA in Pulse Frequency Modulation (PFM) mode, and an adjustable output voltage. The device offers protection features such as Undervoltage Lockout (UVLO), Output Overvoltage Protection (OVP), cycle-by-cycle peak current limit, and thermal shutdown.
The AP63300WU-7 is available in a compact TSOT26 package, suitable for surface mount applications. Its wide input voltage range and efficiency make it suitable for various power bus supplies, consumer electronics, and point-of-load applications.
