LP6218SB6F中文资料High Efficiency 2.6A Boost DC/DC Convertor数据手册LPSemi规格书

描述 Description

The LP6218S is a current mode boost DC-DC converter. Its PWM circuitry with built-in 2.6A current power MOSFET makes this converter highly power efficiently. The LP6218S implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. The LP6218 features automatic shifting to pulse frequency modulation mode at light loads.Highly integration and internal compensation network minimizes as 6 external component counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. The LP6218S includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The LP6218 is available in a small 6-pin SOT23-6 package.
