LP6482S中文资料340KHz, 36V/2.5A Step-down Converter With Soft-Start数据手册LPSemi规格书

描述 Description

The LP6482S 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 2500mA of load current. The LP6482S can also run at 90% duty cycle for low dropout applications. It provides fast transient response and cycle-by-cycle limit with current mode control. And adjustable soft start prevents inrush current at turn on and the supply current drops below 0.1uA in shutdown mode. The LP6482S is available in a SOP8 and ESOP8 package and is rated over the -40°C to 85°C temperature range.
