HX1001AES裕鼎祥咨询电话：139 2843 4054
HX1001 Description
The HX1001 is high efficiency synchronous, PWM step-down DC/DC converters working under an input voltage range of 2.5V to 5.5V. This feature makes the HX1001 suitable for single Li-lon battery-powered applications. 100% duty cycle capability extends battery life in portable devices, while the quiescent current is 230A with no load, and drops to < 1Ain shutdown.The internal synchronous switch isdesired to increase efficiency without an external Schottky diode. The 1.4 MHz fixed switching frequency allows the using of tiny,low profile inductors and ceramic capacitors,which minimized overall solution footprint.The HX1001 converters are available in the industry standard SOT-23-5 power packages (or upon request).
