LP3219
1.5MHz, 2A Step-Down Converter
概述
The LP6483 contains an independent 340KHz constant frequency, current mode, PWM step-down converters. The converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The converter can supply 3A of load current. The LP6483 can also run at 98% duty cycle for low dropout applications. It provides fast transient response and cycle-by-cycle limit with current mode control. The LP6483 is available in a ESOP8 package and is rated over the -40°C to 85°C temperature range.
