General Description
The AP63201 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 AP63201 adopts peak current mode control with the integrated
compensation network, which makes AP63201 easily to be used by minimizing the off-chip component
count..
The AP63201 is an Electromagnetic Interference (EMI) friendly buck converter with implementing
optimized design for EMI reduction. The AP63201 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 AP63201 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.
