DESCRIPTION

The SL3075 is 5A buck converters with wide input voltage, ranging from 4.5V to 65V, which integrates a 90mΩ high-side MOSFET.

The SL3075, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) which assists the converter on achieving high efficiency at light load.The SL3075 features programmable switching frequency from 100kHz to 2MHz with an external resistor.

The SL3075 allows power conversion from high input voltage to low output voltage with a minimum 120ns on-time of switch MOS. The device offers typical 2.5ms soft start to prevent inrush current during the startup.

The SL3075 features external loop compensation to provide the flexibility to optimize either loopstability or loop response.

The SL3075 provides cycle-by-cycle current limit, thermal shutdown protection, output over-voltage protection, output over load protection and input voltage under-voltage protection. The device is available in an ESOP8 package.
