微源热銷 LP6471 600KHz同步降压转换器
General Description
The LP6471 contains an independent 500KHzconstant frequency, current mode, PWM step-down converters.
The converter integrates a main switch anda synchronous rectifier for high efficiency without an external Schottky diode.
The LP6471 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 16V input voltage. The output voltage can be regulated as low as 0.8V.
The LP6471 is available in a SOT23-6 package and is rated over the -40°C to 85°C temperature range.
Applications
◆ Portable Media Players
◆ Cellular and Smart mobile phone
◆ PDA/DSC
◆ GPS Applications
