LP3219
1.5MHz, 2A Step-Down Converter
概述
The LP6470 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 LP6470 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 LP6470 is available in a SOT23-6 package and is rated over the -40°C to 85°C temperature range.
