Diodes Incorporated AP62600 | Demoboard AP62600SJ-EVM

Beschreibung

The AP62600 is a 6A, synchronous buck converter with a wide input voltage range of 4.5V to 18V. The device fully integrates a 36mΩ highside power MOSFET and a 14mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion.The AP62600 device is easily used by minimizing the external component count due to its adoption of Constant On-Time (COT) control to achieve fast transient response, easy loop stabilization, and low output voltage ripple.The AP62600 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.The device is available in a V-QFN2030-12 (Type A) package.
