Краткое описание:
15 V 300 mA synchronous step-down DC/DC converter
Дополнительная информация
Synchronous step-down DC/DC converter supplies up to 300 mA from a 2.5 V to 15 V input range. The output range spans 0.6 V to 13.8 V, and a 1.2 MHz fixed-frequency PWM mode supports low-noise operation. Burst Mode operation reduces typical no-load input supply current to 1.8 µA for light-load efficiency. The device includes internal compensation, programmable RUN threshold, power-good output, integrated soft-start and thermal overload protection.
