The ADP2323 is a dual-channel, 3 A, 20 V synchronous step-down regulator with integrated high-side MOSFETs. Its key features include input voltage range of 4.5 V to 20 V, output accuracy of ±1%, integrated 90 mΩ high-side MOSFETs (typical), flexible output configurations, programmable switching frequency, external synchronization input, programmable phase shift, internal clock output, optional PWM or PFM operating mode, current limiting adjustable for small inductors, external compensation and soft start, and pre-charged output after start-up.
The ADP2323 is a dual‑channel DC‑DC buck regulator that supports input voltages from 4.5 V to 20 V and delivers up to 3 A per channel (6 A in interleaved mode). It integrates high‑performance MOSFETs, offers programmable switching frequency, and includes UVLO, OVP, OCP and thermal‑shutdown protection.
Typical applications include communication infrastructure, servers, industrial instrumentation, and medical equipment where efficient, compact power conversion is required. The device is supplied in a 32‑lead LFCSP_WQ package and operates over a temperature range of –40 °C to +125 °C. This manual is written in Chinese.
