BUCK REGULATOR, AP63203WU-7, TSOT26
Description
The AP63203is a 2A, synchronous buck converter with a wide input voltage range of 3.8V to 32V and 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 AP63203 device is easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated compensation network.
The AP63203 has optimized designs for Electromagnetic Interference (EMI) reduction. The converter 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. It also has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which further erases high-frequency radiated EMI noise caused by MOSFET switching.
Features
•VIN 3.8V to 32V
•2A Continuous Output Current
•0.8V ± 1% Reference Voltage
•22μA Ultralow Quiescent Current
