AP63203中文资料2A Low Iq Synchronous Buck with Enhanced EMI Reduction数据手册Diodes规格书

描述 Description

The AP63200/AP63201/AP63203/AP63205 are 2A, synchronous buck converters with a wide input voltage range of 3.8V to 32V and fully integrates a 125mΩ high-side power MOSFET and a 68mΩ low-side power MOSFET to provide high-efficiency step-down DC/DC conversion.The AP63200/AP63201/AP63203/AP63205 devices are easily used by minimizing the external component count due to their adoption of peak current mode control along with its integrated compensation network.The AP63200/AP63201/AP63203/AP63205 have optimized designs for Electromagnetic Interference (EMI) reduction. The converter features Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time. They also have a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which further erases high-frequency radiated EMI noise caused by MOSFET switching.The devices are available in a low-profile, TSOT26 package.
