【產品特性】4A 5V 1MHz Synchronous Buck Converter
【文字介紹】APW7594 is a 4A synchronous buck converter with integrated 55mW high side and 55mW low side power MOSFETs. The APW7594, design with a current-mode control scheme, can convert wide input voltage of 2.6V to 6V to the output voltage adjustable from 0.6V to 6V to provide excellent output voltage regulation.
The APW7594 is equipped with an automatic PFM/PWM mode operation. At light load , the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM mode. At PWM mode, the switching frequency is set by the external resistor.
The APW7594 is also equipped with Power-on-reset, softstart, soft-stop, and whole protections (under-voltage,over-voltage, over-temperature and current-limit) into a single package.
This device, available TDFN3x3-10, provides a very compact system solution external components and PCB area.
