NN30500A-VB [Panasonic]

The NN30500A is a 2-Channel synchronous DC-DC step-down regulator featuring hysteretic control for high-speed response to load current changes. It integrates four power MOSFETs (20 mΩ typical for both high-side and low-side) to deliver up to 6A per channel with high efficiency. The device supports an input voltage range of 4.5V to 24V and adjustable output voltage from 0.75V to 5.5V. Key features include skip mode for light-load efficiency, 600 kHz optimized switching frequency, internal soft-start, a built-in 2.5V/100mA LDO (PHY), and external MOS control switches. It requires no external compensation components, reducing external part count and enabling compact designs. Comprehensive protection features include UVLO, thermal shutdown, over/under-voltage detection, over-current protection, and short-circuit protection. The device is housed in a compact 32-pin QFN package (4mm x 5mm x 0.8mm).
