The LM5022 high-voltage, low-side N-channel MOSFET controller is ideal for use with boost and SEPIC regulators. It contains all the required functions to implement a single-ended primary topology. Output voltage regulation is based on current mode control, simplifying loop compensation design while providing inherent input voltage feedforward. The LM5022 includes a start-up regulator over a wide input voltage range of 6V to 60V. The PWM controller is designed for high-speed capabilities, including oscillator frequency ranges up to 2 MHz and total propagation delays of less than 100 ns. Other features include an error amplifier, high-precision reference, line undervoltage lockout, cycle-by-cycle current limit, ramp compensation, soft-start, external synchronization capability, and thermal shutdown. The LM5022 is available in an MSOP-10 package.
