LM5022MM/NOPB .

The LM5022MM/NOPB is a Current-mode Boost and SEPIC Controller. The LM5022 is a high voltage low-side N-channel MOSFET controller ideal for use in boost and SEPIC regulator. It contains all of the features needed to implement single ended primary topologies. Output voltage regulation is based on current-mode control, which eases the design of loop compensation while providing inherent input voltage feed-forward. The LM5022 includes a start-up regulator that operates over a wide input range of 6V to 60V. The PWM controller is designed for high speed capability including an oscillator frequency range up to 2MHz and total propagation delays less than 100ns. Additional features include an error amplifier, precision reference, line under-voltage lockout, cycle-by-cycle current limit, slope compensation, soft-start, external synchronization capability and thermal shutdown.
