The SP1N28, adopting the peak current mode control. The SP1N28 features programmable switching frequency from 100 k Hz to 1.1 MHz with an external resistor, which provides the flexibility to optimize either efficiency or external ponent size. The converter supports external clock synchronization with a frequency band from 100k Hz to 1.1MHz. The SP1N28 allows power conversion from high input voltage to low output voltage with a minimum 100ns on-time of highside MOSFET. The SP1N28 supports Force Pulse Width Modulation (FPWM) Mode to achieve the small output ripple at light load condition. The SP1N28 offers cycle-by-cycle current limit and hiccup over current protection, thermal shutdown protection, output over-voltage protection and input voltage under-voltage protection. The device is available in an 8-pin thermally ESOP-8 package. TYPICAL APPLICATION C3...
