Hot-selling and scarce LM5034MTCX High Voltage Dual Interleaved Current Mode Controller IC TSSOP20 spot stock

Product Descriptions

The LM5034 dual current mode PWM controller contains allthe features needed to control   either  two independentforward/active clamp dc/dc converters or a single high current converter comprised of two interleaved power stages .The two controller channels operate 180˚ out  of  phasethereby reducing input ripple current . The LM5034 includes astartup regulator that operates over a wide input range up to100V and compound (bipolar + CMOS) gate drivers thatprovide a robust  2.5A peak sink current . The adjustabledead-time of the active clamp gate drivers and adjustablemaximum PWM duty cycle reduce stress on the primary sideMOSFET switches .  Additional  features include programmable line under-voltage lockout,  cycle-by-cycle currentlimit,  hiccup mode fault  operation with adjustable restartdelay, PWM slope compensation, soft-start, and a 2 MHzcapable oscillator with synchronization capability.
