Diodes Incorporated AP64501
The AP64501 is a 5A, synchronous buck converter with a wide input voltage range of 3.8V to 40V. The device fully integrates a 45mΩ highside power MOSFET and a 20mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP64501 device is easily used by minimizing the external component count due to its adoption of peak current mode control.| Part No. | AP64501 |

DESCRIPTION
Pin Assignments The AP64501 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. AP64501 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. BST 1 VIN 2 EN 3 SS 4 TOP VIEW EXPOSED PAD 9 SO-8EP 8 SW 7 GND 6 COMP 5 FBFEATURES
