SCT芯洲 SCT9336 5A同步降壓DCDC轉(zhuǎn)換器
DESCRIPTION
The SCT9336 is 5A synchronous buck converters with up to 28V wide input voltage range, which fully integrates an 85mΩ high-side MOSFET and a 58mΩ low-side MOSFET to provide high efficiency step-down DCDC conversion. The SCT9336 adopts peak current mode control with the integrated compensation network, which makes SCT9336 easily to be used by minimizing the off-chip component count. The SCT9336 supports the Pulse Skipping Modulation (PSM) with typical 20uA Ultra-Low Quiescent.
The SCT9336 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT9336 features Frequency Spread Spectrum FSS with ±6% jittering span of the 400kHz 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 SCT9336 offers output over-voltage protection, cycle-by-cycle peak current limit, and thermal
shutdown protection. The device is available ESOP-8 package.
