1.5MHz, 2A Synchronous Step-Down Converter CXSD61042S is a 1.5MHz constant frequency, current mode step-down converter. It is ideal for portable equipment requiring very high current up to 2A

   产品概述 返回TOPqqy嘉泰姆

The CXSD61042S is a 1.5MHz constant frequency, current mode step-down converter. It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions. The CXSD61042S also can 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 CXSD61042S can supply up to 2A output load current from a 2.3V to 6V input voltage and the output voltage can be regulated as low as 0.6V. The high switching frequency minimizes the size of external components while keeping switching losses low. The internal slope compensation setting allows the device to operate with smaller inductor values to optimize size and provide efficient operation. The device is available in a Pb-free, SOP8 package and is rated over the -40°C to +85°C temperature range. 

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.
