EM5305

12V Synchronous Buck controller General Description The EM5305 series are compact synchronous -rectified buck controllers specifically designed to operate from 5V or 12V supply voltage. The output voltage is tightly regulated to the external reference voltage from 0.4V to 3.0V. These devices operate at fixed 300 kHz frequency and provide an optimal level of integration to redwuce size and cost of the power supply. The controllers integrate internal MOSFET drivers that support 12V+12V bootstrapped voltage for high efficiency power conversion. The bootstrap diode is built-in to simplify the circuit design and minimize external part count. Other features include internal soft-start, under-voltage protection, over-voltage protection, over-current protection and shutdown function. With aforementioned functions, these parts provide customers a compact, high efficiency, well-protected and cost-effective solutions. These parts are available in DFN3x3-10L package.
