供应LP6481 微源400KHz同步降压转换器

微源半导体 LP6481 SOP-8 400KHz，16V/2A同步降压转换器

General Description

The LP6481 contains a independent 400KHz constant frequency, current mode, PWM step-down converters. The converter integrates a main switch and asynchronous rectifier for high efficiency without an external Schottky diode. The LP6481 is ideal for powering portable equipment that runs from a 2cell Lithium-Ion (Li+) battery. The converter can supply 2000mA of load current from a 4.5V to 18V input voltage. The output voltage can be regulated as low as 0.8V. The LP6481 can also run at 100％ duty cycle for low dropout applications.The LP6481 is available in a SOP8 and ESOP8 package and is rated over the -40°C to 85°C temperature range.
