LP6482SOF 微源降压转换器 无铅环保型芯片

General description

The LP6482 contains an independent 340KHz constant frequency, current mode, PWM step-down converters. The converter integrates a main switch and synchronous rectifier for high efficiency without an external schottky diode. The converter can supply 2A of load current. The LP6482 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 LP6482 is available in a SOP8package and is rated over the -40°C to 85°C temperature range.
