AP63203Q Datasheet | Diodes Incorporated

Description The AP63200Q/AP63201Q/AP63203Q/AP63205Q is an automotivepliant, 2A, synchronous buck converter with a wide input voltage range of 3.8V to 32V. The device 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 AP63200Q/AP63201Q/AP63203Q/AP63205Q device is easily used by minimizing the external ponent count due to its adoption of peak current mode control along with its integrated loop pensation network. The AP63200Q/AP63201Q/AP63203Q/AP63205Q 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 highfrequency radiated EMI noise caused by MOSFET switching. The AP63200Q/AP63203Q/AP63205Q 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 a TSOT26 package.
