The SCT2320 is a high power density, 2A synonous buck converter with input 3.8V to 32V input range. The device is EMI friendly features ultra-low quiescent operating current.
The device fully integrates a 140mΩ high-side MOSFET a 70mΩ low-side MOSFET to provide high efficiency step-down DCDC conversion. The Pulse Skipping Modulation (PSM) with 20uA ultra low quiescent current improve the power efficiency up to 88% at 5mA load.
The SCT2320 implements Frequency Spread Spectrum (FSS) with ±6% jittering span of the 500 KHz switching frequency modulation rate 1/512 of switching frequency to reduce conduction Electromagnetic Interference (EMI). Optimized gate driver scheme achieves voltage ringing free at SW node to reduce high frequency radiation EMI. The SCT2320 adopts peak current mode control with the internal integrated compensation network, which makes it easy to be used by minimizing the off-chip component count. The SCT2320 features output over-voltage protection, cycle-by-cycle peak current limit, thermal shutdown protection. The device is available in a low-profile TSOT23-6 package.
