   产品概述 返回TOPqBe嘉泰姆

The CXSD61043S is a constant frequency, current mode step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. The CXSD61043S can supply up to 3A output load current from a 2.3V to 6V input voltage and the output voltage can be regulated as low as 0.6V. The CXSD61043S can also run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications. The internal slope compensation setting allows the device to operate with smaller inductor values to optimize size and provide efficient operation. The CXSD61043S is available in adjustable (0.6V to VIN) output voltage. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.
