AP63203WU-7
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the AP63203WU-7 family does
The AP63200/AP63201/AP63203/AP63205 is a 2A synchronous buck converter operating from 3.8V to 32V inputs. It integrates high-side and low-side MOSFETs, offering 500kHz or 1.1MHz switching frequencies with up to 88% efficiency. The device supports fixed 3.3V or 5.0V outputs and features Frequency Spread Spectrum for EMI reduction. Engineers typically use it for distributed power bus supplies, flat screen TV sets, power tools, laser printers, white goods, home audios, network systems, set top boxes, gaming consoles, and consumer electronics. Its low quiescent current of 22µA makes it ideal for battery-powered applications requiring high efficiency at light loads.
