特点Wide Input Range: 3V to 25VProgrammable Volt-Second ClampOutput Power Levels from 25W to 500W Auxiliary Boost Converter Provides 10V Gate Drive from V IN as Low as 3V Programmable Operating Frequency (100kHz to 500kHz) with One External ResistorProgrammable Slope CompensationProgrammable Leading Edge Blanking±2% Internal 1.23V ReferenceAccurate Shutdown Pin Threshold with Programmable Hysteresis60ns Current Sense Delay2.5V Auxiliary Reference Output Synchronizable to an External Clock up to 1.5 ? f OSC Current Mode ControlSmall 16-Pin SSOP Package典型应用典型应用描述The LT?1950 is a wide input range, forward, boost, flyback and SEPIC controller that drives an N-channel power MOSFET with few external components required.A resistor programmable duty cycle clamp can be used to generate a volt-second clamp for forward converter applications. An internal boost switcher is available for creating a separate supply for the output gate driver, allowing 10V gate drive from input voltages as low as 3V. The LT1950’s operating frequency can be set with an external resistor over a 100kHz to 500kHz range and a SYNC pin allows the part to be synchronized to an external clock. Additional programmability exists for leading edge blanking and slope compensation.A fast current sense comparator achieves 60ns current sense delay and the error amplifier is a true voltage mode error amplifier, allowing a wide range of compensation networks. An accurate shutdown pin with programmable hysteresis is available for undervoltage lockout and shutdown. The LT1950 is available in a small 16-Pin SSOP package.
