供应微源 LP6483SPF 3A降压转换芯片

微源半导体 LP6483SPF ESOP8 340KHz，带软启动的3A降压转换器

General Description

The LP6483SPF 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 LP6483SPF 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 LP6483SPF is available in a ESOP8 package and is rated over the -40°C to 85°C temperature range.
