LP6230B数据手册LPSemi中文资料规格书

描述 Description

The LP6230B is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.16Ω, 2.4A current power MOSFET makes this converter highly power efficiently. The LP6230B implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. The LP6230B 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 LP6230B includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The LP6230B is available in a small 8-pin MSOP8 package.
