Guangzhou ZLGMCU Development Co., Ltd. provides you with a selection guide for the full range of MCU peripheral components.
This guide, prepared by Guangzhou ZLG MCU Development Co., Ltd., introduces the most common power‑converter topologies used in AC‑DC and DC‑DC applications. It describes the characteristics of FlyBack, Forward, Half‑Bridge, Push‑Pull, Full‑Bridge, Buck, Boost, and Buck‑Boost converters, helping engineers choose the right architecture.
The document also lists numerous ON Semiconductor parts with their key specifications, such as input voltage range, switching frequency, and package type. Tables provide quick reference data for devices like LM2596, NCP series, and NCV series, supporting selection for a wide range of applications from portable electronics to industrial equipment. This manual is written in Chinese.
| LM2596 Switching frequency | 150 kHz |
|---|---|
| NCP3064 Switching regulator output current | 1.5 A |
The common AC‑DC topologies are FlyBack, Forward, Half‑Bridge, Push‑Pull, and Full‑Bridge.
Typical DC‑DC topologies include Buck, Boost, Buck‑Boost, and Flyback converters.
High‑efficiency DC‑DC converters waste less power as heat, improving overall efficiency and reducing thermal issues compared to LDOs.
The LM2596 series (e.g., LM2596DSADJG) offers a 150 kHz, 3 A step‑down voltage regulator.
