Beschreibung

The AP63200 is a 2A, synchronous buck converter with up to 32V wide input voltage range, which fully integrates a 140mΩ high-side MOSFET and a 70mΩ low-side MOSFET to provide high efficiency step-down DC/DC conversion. The AP63200 adopts peak current mode control with the integrated compensation network, which makes AP63200 easily to be used by minimizing the off-chip component count. The AP63200 supports the Pulse Skipping Modulation (PSM) with typical 22uA Ultra-low Quiescent and achieved high efficient performance at light load conditions.The AP63200 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The AP63200 features Frequency Spread Spectrum (FSS) with ±6% jittering span of the 500 kHz switching frequency and modulation rate 1/512 of switching frequency to reduce the conducted EMI. The converter has proprietary designed gate driver scheme to resist switching node ringing without sacrificing MOSFET turn on and turn off time, which further erases high frequency radiation EMI noise caused by the MOSFETs hard switching.The AP63200 offers output overvoltage protection, cycle-by-cycle peak current limit, and thermal shutdown protection. The device is available in a low-profile TSOT23-6 package.
