DESCRIPTION：

 

The SCT2331C is 3A synchronous buck converters with up to 28V wide input voltage range, which fully integrates an 80mΩ high-side MOSFET and a 42mΩ low-side MOSFET to provide high efficiency step-down DC-DC conversion. The SCT2331C adopts peak current mode control with the integrated compensation network, which makes SCT2331C easily to be used by minimizing the off-chip component count. The SCT2331C supports the Forced PWM mode (FPWM) with typical 200uA Quiescent Current. 
The SCT2331C is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2331C 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 SCT2331C offers output over-voltage protection, cycle-by-cycle peak current limit, and thermal shutdown protection. The device is available in a low-profile TSOT23-6L package.
