The SCT9339 is 3A synonous buck converters with up to 30V wide input voltage range, which fully integrates an 85mΩ high-side MOSFET a 58mΩ low-side MOSFETto provide high efficiency step-down DCDC conversion. The SCT9339 adopts peak current mode control with the integrated compensation network, which makes SCT9339 easily to be used by minimizing the off-chip component count. The SCT9339 supports Force Pulse Width Modulation (FPWM) Mode to achieve the small output ripple at light load condition. The SCT9339 offers output over-voltage protection, cycle-by-cycle peak current limit, thermal shutdown protection. The device is available ESOP-8 package.
