Product Introduction
The AP64350 is a 3.5A, synchronous buck converter with a wide input voltage range of 3.8V to 40V. The device fully integrates a 75mΩ high- side power MOSFET and a 45mQ low- side power MOSFET to provide high- efficiency step- down DC- DC conversion.
The AP64350 device is easily used by minimizing the external component count due to its adoption of peak current mode control.
The AP64350 design is optimized for Electromagnetic Interference (EMI) reduction. The device has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn- on and turn- off times, which reduces high- frequency radiated EMI noise caused by MOSFET switching. AP64350 also 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.
The device is available in an SO- 8EP package.
