LX3005CDM中文资料Step-Down Buck Regulators数据手册Microchip规格书

描述 Description

The LX3005 is a 420kHz fixed frequency PWM buck (step-down) DC-DC converter, capable of driving a 2A load with high efficiency, low ripple and excellent line and load regulation. The device operates over a wide input voltage range of 4.75V to 25V. The LX3005 serves as an ideal power supply device for portable devices, especially for chipset power in portable systems. It’s widely used for PDVD, LCD monitor and DPF chipset power sources. The LX3005 is available in SOIC8 package and is functional from an ambient temperature range of 0oC to 85oC.FEATURES:
