LM5022-Q1 (ACTIVE) 6-60V Wide Vin, Current Mode Boost, SEPIC and Flyback Controller

 

Description

The LM5022-Q1 is a high voltage low-side N-channel MOSFET controller ideal for use in boost and SEPIC regulators. 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-Q1 includes a start-up regulator that operates over a wide input range of 6 V to 60 V. The PWM controller is designed for high-speed capability including an oscillator frequency range up to 2.2 MHz and total propagation delays less than 100 ns. Additional features include an error amplifier, precision reference, line undervoltage lockout, cycle-by-cycle current limit, slope compensation, soft-start, external synchronization capability, and thermal shutdown. The LM5022-Q1 is available in the 10-pin VSSOP package.
