HX1006 详细介绍
相关商品: HX1001AES
The HX1006 is a dual channel, constant frequency, synchronous step-down DC/DC converter. Intended for low power applications, it operates from 2.5V to 5.0V input voltage range and has a constant 1.5MHz switching frequency, enabling the use of tiny, low cost capacitors and inductors 1mm or less in height. Each output voltage is adjustable from 0.6V to 4.2V. Internal synchronous 0.35&https://lsdtek.com/brand-id-6-cat-12/486;, 1A power switches provide high efficiency without the need for external Schottky diodes.  
The current mode operation achieves fast line and load transient response. To maximize battery life, the p-channel MOSFETs are turned on continuously in dropout (100% duty cycle), and both channels draw a total quiescent current of only 250μA for each output. In shutdown, the device draws <1μA.
