Diodes Incorporated AP64500
The AP64500 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 AP64500 device is easily used by minimizing the external component count due to its adoption of peak current mode control.- Min Voltage : 3.8V
- Max Voltage : 40V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C

DESCRIPTION
Pin Assignments The AP64500 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. AP64500 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 RT/CLK 4 TOP VIEW EXPOSED PAD 9 SO-8EP 8 SW 7 GND 6 COMP 5 FBFEATURES
