Product Overview

The LT1950EGN#PBF is a single Switch PWM Controller with auxiliary boost converter. This forward boost flyback and SEPIC controller 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 100 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.
